[Tutor] Plot trajectories on an map using matplotlib-basemap

 with the above code I get an array whose columns represent: [Lat, Lon, Date, 
Identifier, Temperatures, Category]. Now, I will put a code that allows me to 
plot the first and second column on the map of Mexico:



#!/usr/bin/python
#Project Storm: Plot trajectories of convective systems
#import libraries

import numpy as np
from mpl_toolkits.basemap import Basemap
import  matplotlib.pyplot as pl

# Plot a map for Mexico

m = Basemap(projection='cyl', llcrnrlat=12, urcrnrlat=35,llcrnrlon=-120, 
urcrnrlon=-80, resolution='c', area_thresh=1000.)
m.bluemarble()
m.drawcoastlines(linewidth=0.5)
m.drawcountries(linewidth=0.5)
m.drawstates(linewidth=0.5)

#Draw parallels and meridians

m.drawparallels(np.arange(10.,35.,5.))
m.drawmeridians(np.arange(-120.,-80.,10.))
m.drawmapboundary(fill_color='aqua')

#Open file whit numpy

data = np.loadtxt('path-tracks.csv', dtype=np.str,delimiter=' , ', 
skiprows=1)
latitude = data[:,0]
longitude = data[:,1]

#Convert latitude and longitude to coordinates X and Y

x, y = m(longitude, latitude)

#Plot the points on the map

pl.plot(x,y,'ro-')
pl.show()



The points plotted on the map, corresponding to three different paths with a 
line connecting all points. Mi final idea is to draw a line connecting the 
points associated with each path, How  I can do this? or How should I structure 
my data to plot the different paths?

is posible draw an identifier or a mark for each path?


how I can set the size of the figure so that it can distinguish the separation 
between the points?

A direct approach would probably use the webdriver API to automate the
browser.  Selenium has one:

http://selenium.googlecode.com/svn/trunk/docs/api/py/index.html

That being said, I agree with you that this is most likely an overkill
approach.  Better to see if the site has an officially supported
REST-style API that can be more easily mechanized.

That's because Javascript is run in the browser which has a Javascript 
interpreter built in. Python doesn't have a Javascript interpreter so 
can't run Javascript.


But that's usually the wrong thing to do anyway so it doesn't matter. 
What you need to do is figure out what the Javascript is doing - usually 
sending some data to a server - and replicate that.


Alternatively fire up a real browser and drive that with automation. How 
you do that will largely depend on the browser and the OS.

[Tutor] automate add-to-cart with python

[Benjamin Fishbein]

Hello,
I'm trying to automate putting a series of items into my cart. Here's the html 
for the add-to-cart button on the website:
http://cart.half.ebay.com/ws/eBayISAPI.dll?HalfAddItemToCart&ap=additem&itemid=343343950913&pr=57017296&fromshop=1";>Add
 to cart
Using the cookielib and urllib2 module, I did:

a= text.find("href")+6
b = text.find('"', a)
url = text[a:b]
new_text = opener.open(url).read()

It goes to the page that shows my cart, but there are zero items--the item is 
not added to the cart.
I'm guessing this has something to do with:

class="PDP_button_addToCart2"

I'm not sure how to have Python click the button.
In general, despite scouring the Internet, I haven't been able to figure out 
how to get Python to cause javascripts I find in the html to be run.
Any help would be greatly appreciated.
Thanks,
Ben

Do you have an idea of what kind of things would be useful test cases
for this converter?  Thinking about this may help solidify what it is
you're trying to do.  By it, we want to help you express concretely
what you mean when you say "binary/decimal converter".

---

For example, if I wanted to write a program to convert "snow" to
"water", I might start like this:

I want to write a program to take words like "snow" and rewrite them
to "water".  But anything else should stay the same.  Let me give a
name to this.  Call it "melt".  Here are some examples I'd like to
make work (or not work).

melt("The snow is cold!")  ==> "The water is cold!"
melt("The snowflakes are falling") ==>  "The snowflakes are falling"
melt("Snow and ice") ==>  "Water and ice"

That is, I want to make sure the translation is case sensitive, but
only applies when the whole word "snow" shows up.


... etc.  A potential approach might use regular expression
replacement, with a little bit of care about using a function for the
replacement argument so we can handle the weird uppercasing
requirement...

---


If you plan like this, and include concrete test cases, then you'll
have a better shot at solving the problem.

Ghadir,

I did a quick google search for how to convert digital to binary. The 
first link was to 
http://www.ehow.com/how_5164721_convert-digital-binary.html which gives 
a pretty clear example of the process for converting digital to binary.  
Of course, you will need to translate this psuedo-code into an algorithm 
using Python.

I would like to emphasize that regex is an entirely wrong approach for
this task. The reason is that it's very brittle, hard to read, hard to
debug and update if the text file changes. The first step should be to
simplfy the task -- in this case, to split the string into lines and
strip each line.

List comps as shown by Oscar is the best approach, but if you don't feel
comfortable with list comps, you can then use a loop:

lst = []
for line in junk_list:
if line == "auto"  : lst.append(line)
elif line.startswith("10") : lst.append(line)
elif line.startswith("40") : lst.append(line)

You could even use a regex as part of the loop:

for line in junk_list:
if re.match("^(auto|10|40)", line):
lst.append(line)

It's still much better than using a humongous regex.

Here's my attempt:

Got it Oscar.  Thank you for your respectful corrections and your solution.
 I used "Rich Text" which is what  I thought was recommended by the list gurus 
at one point.   Plain Text it is then.

Your response definitely does the trick and I can use that as a base for the 
future.

As per Joel's comment that it is a variation of questions I asked in the past, 
right you are.   I had to put this away for a while and am picking it up again

This looks like a variation on the questions you asked over the last couple
of months.  Printing junk_list I get this:

>>> print junk_list
pabilitiesnet interface 1.3 media-ca
net interface 1.3 {
media-capabilities {
none
auto
 4SR4-FD
  10T-HD
100TX-FD
100TX-HD
1000T-FD
4LR4-FD
 1000T-HD
}
}
How do you get junk_list?  Read from a file?  Is there more in the file
besides what is in junk_list?  Do you have this exact file format every
time?

You might do better to use readline() instead of read(), and strip() each
line so that you don't have the new line issue.  I'm guessing but it looks
like you can toss every line until you get past media-capabilities, and
toss every line that contains }.  But maybe I am reading more into the data
format than is appropriate.

If my guesses are correct, you don't need regex stuff at all, because each
line (that you don't toss) contains something you want, and you can build
you list

Those \xc2\xa0 characters are non-breaking space characters. The
trouble is that I don't know if they were added by your email client
or are actually part of your junk string. I've assumed the former and
replaced them with spaces in the code I show below.

This output doesn't match what I would expect from the string above.
Why is '1000T-FD' after '4LR4-FD'? Is that the problem with the
code you posted?

Does "any number" mean "one or more" or "zero or more"?

Some people like to use regexes for everything. I prefer to try string
methods first as I find them easier to understand. Here's my attempt:

>>> junk_list = 'tmsh list net interface 1.3 media-ca \rpabilities\r\nnet 
>>> interface 1.3 {\r\nmedia-capabilities {\r\nnone\r\n
>>> auto\r\n 4SR4-FD\r\n  10T-HD\r\n100TX-FD\r\n
>>> 100TX-HD\r\n1000T-FD\r\n4LR4-FD\r\n 1000T-HD\r\n
>>> }\r\n}\r\n'
>>> junk_list = [s.strip() for s in junk_list.splitlines()]
>>> junk_list = [s for s in junk_list if s == 'auto' or s[:2] in ('10', '40')]
>>> junk_list
['auto', '4SR4-FD', '10T-HD', '100TX-FD', '100TX-HD', '1000T-FD',
'4LR4-FD', '1000T-HD']

Does that do what you want?

[Tutor] Question on re.findall usage

[Dave Wilder]

Hello,

I am trying using re.findall to parse the string below and then create a list 
from the results.
junk_list = 'tmsh list net interface 1.3 media-ca \rpabilities\r\nnet interface 
1.3 {\r\nmedia-capabilities {\r\nnone\r\nauto\r\n 
4SR4-FD\r\n  10T-HD\r\n100TX-FD\r\n100TX-HD\r\n
1000T-FD\r\n4LR4-FD\r\n 1000T-HD\r\n}\r\n}\r\n'

What I am doing now is obviously quite ugly, but I have not yet able to 
manipulate it to work how I want but in a much more efficient and modular way.
I did some research on re.findall but am still confused as to how to do 
character repetition searches, which  I guess is what I need to do here.
>> junk_list = 
>> re.findall(r'(auto|[1|4]0+[A-Z]-[HF]D|[1|4]0+[A-Z][A-Z]-[HF]D|[1|4]0+[A-Z][A-Z][0-9])',
>>  junk_list)
>> junk_list
['auto', '4SR4', '10T-HD', '100TX-FD', '100TX-HD', '4LR4', '1000T-FD', 
'1000T-HD']
>>>

Basically, all I need to search on is:
-   auto
-   anything that starts w/ '1' or '4' and then any number of subsequent 
zeroes   e.g. 10T-HD, 4LR4-FD, 100TX-FD

My environment:

1. Code indentation was lost in your message.  Everything below is
based on guessing, guessing and guessing.
2. In order to get user data, do (assuming Python 2):

import getpass
self.email= raw_input('E-mail address: ')
self.password = getpass.getpass('Password: ')
devcode = raw_input(Developer access code: ')

Although you should provide the user with the tokens, using the same
methods REAL developers use, i.e. app authentication.

There is a third part module for this, a Google search for pyPDF should

raw_input()?

Before doing too much work on such an app, consider if you're violating 
Facebook's terms of service.  The following links may not be the right 
ones, but it could get you started thinking, anyway.


http://developers.facebook.com/blog/post/2013/01/25/clarifying-our-platform-policies/
http://www.facebook.com/help/131112897028467/

As for creating a pdf from a simple text list, I think you'd be best 
shelling out to a program that does just that.  Naturally, the choices 
vary by OS, and I have not recommendations.


As for username and password, why not use raw_input ?

Just to clarify, the '%' should go in the parameter string, not
as part of the query string. The query string should retain the '?'
(without any quotations).

[Tutor] Facebook login using python

[Aaron Misquith]

I am working on a program which is used to login to facebook, get my friend
lists using graph api and export them into pdf format.
So far i'm able to login with facebook and get the friend list. I would
like if someone is able to provide me a code to export the output to pdf.

You can supply a custom function as the type to the add_argument() method:

http://docs.python.org/2/library/argparse.html#type

Here's a basic example:

$ cat argparse_intrange.py
import argparse

def check_range(arg):
try:
value = int(arg)
except ValueError as err:
   raise argparse.ArgumentTypeError(str(err))

if value < 0 or value > 1:
message = "Expected 0 <= value <= 1, got value = {}".format(value)
raise argparse.ArgumentTypeError(message)

return value

if __name__ == "__main__":
parser = argparse.ArgumentParser()
parser.add_argument("alpha", type=check_range, nargs="?")

print(parser.parse_args())

$ python argparse_intrange.py 
Namespace(alpha=None)
$ python argparse_intrange.py 100
Namespace(alpha=100)
$ python argparse_intrange.py -100
usage: argparse_intrange.py [-h] [alpha]
argparse_intrange.py: error: argument alpha: Expected 0 <= value <= 1, got 
value = -100
$ python argparse_intrange.py 10
usage: argparse_intrange.py [-h] [alpha]
argparse_intrange.py: error: argument alpha: Expected 0 <= value <= 1, got 
value = 10
$ python argparse_intrange.py x
usage: argparse_intrange.py [-h] [alpha]
argparse_intrange.py: error: argument alpha: invalid literal for int() with 
base 10: 'x'

If you want to use check_range() with arbitrary ranges you can parameterise it:

import functools

def check_range(arg, min, max):
# your code

check_range_alpha = functools.partial(check_range, min=0, max=1)
check_range_beta = functools.partial(check_range, min=-10, max=10)

parser = argparse.ArgumentParser()
parser.add_argument("alpha", type=check_range_alpha, nargs="?")
parser.add_argument("beta", type=check_range_beta, nargs="?")

Python is a byte-code compiled language, like Java many years ago. Normally to 
compile a python module, you just import it from within Python.

That is not very convenient for scripts, so from the shell (bash, command.com, 
cmd.exe, or similar) you can run

python -m compileall NAME NAME ...

to compile scripts.


You do not necessarily need to set the PYTHONPATH, but you can if you need to.

.py files are source code. .pyc are compiled byte code. .pyo are compiled byte 
code with optimization turned on. Don't get too excited, the standard Python 
optimization doesn't do very much.
