[Tutor] Running a python script from another python script
Hello,
I am a newbee in python and trying to make a small script for my school
project . I try to run a python cgi script from another phyton script
as a result of an action . What is the neccesary command for this action
and is there a special class have to be imported for this command.
below i am giving so for what i have writen and what am i trying to do.
Thant you for your help
this is my first script for a basic log in action. i want to run the
second script from this script as a result of login action
# index.cgi# login script
#!/usr/bin/python
import cgi
print "Content-Type: text/html\n\n"
# Define function to generate HTML form.
def generate_form():
print "\n"
print "\n"
print "\tInfo Form\n"
print "\n"
print "\n"
print "\tPlease, enter your UserName and Password.\n"
print "\t\n"
print "\t\t\n"
print "\t\tUserName:\n"
print "\t\tPassword:\n"
print "\t\n"
print "\t\n"
print "\t\n"
print "\t\n"
print "\n"
print "\n"
# Define main function.
def main():
form = cgi.FieldStorage()
if (form.has_key("action") and form.has_key("UserName") and
form.has_key("Password")):
if (form["UserName"].value == "sinan" and form["Password"].value== "666"):
print "Welcome Boss !!"
here i need a command to move on my second script
(index1.cgi)#
else:
print " You are not recognized !!"
generate_form()
else:
print " You are not recognized !!"
generate_form()
main()
## index1.cgi # this is my second script whish has
to be runned from the first script
as a result of login action#

Re: [Tutor] Defining functions
Try this.
import sys
def my_raw_input(prompt):
sys.stdout.write(prompt)## Since they're thinking of bonking off
print as well.
a = sys.stdin.readline()
if a.startswith(prompt):
return a[:len(prompt)]
return a
It leaves the '\n' on the end... so it sucks.
I know there is a better way... Someone else-help?
Jacob
So, as a newbie, I see this thread and I check out the PEP and I see
that for future compatibility we should use sys.stdin.readline(). So
I import sys to see how it works. Of course, sys.stdin.readline('type
anything: ') doesn't work in quite the same way as raw_input('type
anything: ') does. The closest I can get after a few newbie stabs is:
print 'type anything: ', sys.stdin.readline()
type anything: hello
hello
What is the easiest way to get the exact functionality of raw_input()
(i.e. a prompt, no whitespace at the front, and no trailing \n) using
sys.stdin.readline()?

Yeah. And they're thinking of removing raw_input() too. I think it's
good
to have a __builtin__ user input function. Why should we have to import
sys everytime we want user input? Almost every program that newbies write
uses it, and advanced programmers also if they're using console programs.
IMHO, I see no reason to remove it.

Thanks for that, I've installed mxDateTime, and just playing around at
the >>> with it, I can see that it's very useful, and being able to
pass it as a parameter is just what I needed.
And yeah, I'm familiar with the (lack of) documentation for pysqlite.
Apparently a whole new version is in the works, based around the
latest SQLite release, and it's a one man show as far as I can tell,
so perhaps I should get my skills up to speed and write the docs. : )

Just a quick query. I want to store dates and work with them in my SQLite database. There's no specific need for any calculations to done on one side or another (i.e. it's a single user database). I googled how to work with dates in SQL, and I got one like this - SELECT * FROM totp WHERE wk BETWEEN '1980/05/20' AND '1980/05/26' as an example of finding a range for a date. I'm not too sure about how SQL works with dates (and times for that matter), so I'm tempted to stick to what I know and just store dates/times as strings in the db, and then use them to create datetime objects when needed. I have not worked much with sqlite, but from this page: http://www.sqlite.org/datatype3.html it appears that sqlite does not have a date datatype. theDateTime = datetime.datetime(intD[0], intD[1], intD[2], intT[0], intT[1]) Although working with dates like that doesn't seem that flash either. Well... create a wrapper function to clean it up, right? Alternatively, I was thinking of storing the actual datetime object in the database (this is a blob I believe?), and that's a whole new kettle of fish.

What kind of games, for what platform? Obviously you could write a text-based game without PyGame. You can do simple animations in Tkinter - see http://effbot.org/zone/tkinter-animation.htm and http://www.astro.washington.edu/owen/TkinterSummary.html#After. You can play sounds with WinSound. My guess is that for a complex game you will want things that pygame supplies like double-buffered drawing and an event system. Just a guess though, I haven't done this myself.

Liam, SQL is another language. You need to learn it like you are
learning Python. It has pretty decent support for dates and times as
part of the ANSI SQL spec.
There are defined types, SQL functions, etc.
week(date) = week(mydate) for instance.
I tend to prefer to write programming language agnostic databases
because that way I can interact with them from any random language I
need to. Sometimes things go bad and a quick little script which does:
rows = exec("select * from table")
exec("begin transaction")
for row in rows:
row[3] = row[2] + row[4] - 5 # we decided on a new value
exec("update fields in table")
can be handy.

Re: [Tutor] re question
I don't know why this isn't working for you but this worked for me at a DOS
console:
>>> s='850hPa±'
>>> s
'850hPa\xf1'
>>> import re
>>> re.sub('\xf1', '*', s)
'850hPa*'
>>> import sys
>>> sys.stdout.encoding
'cp437'
and also in IDLE with a different encoding:
>>> s='850hPa±'
>>> s
'850hPa\xb1'
>>> import re
>>> re.sub('\xb1', '*', s)
'850hPa*'
>>> import sys
>>> sys.stdout.encoding
'cp1252'
So one guess is that the data is in a different encoding than what you expect? When you print the
string and get '\xb1', is that in the same program that is doing the regex?
Another approach would be to just pull out the numbers and ignore everything
else:
>>> s='Std Lvl: 850hPa, 1503m, 16.8C, 15.7C, 205 @ 11kts'
>>> l=s.split(',')
>>> l
['Std Lvl: 850hPa', ' 1503m', ' 16.8C', ' 15.7C', ' 205 @ 11kts']
>>> [ re.search(r'[\d\.]+', i).group() for i in l]
['850', '1503', '16.8', '15.7', '205']

I am using the following cleanstring = re.compile( '(hPa|hPa\xb1|m|C|kts)'
). And then the cleanstring.sub("",line). I have tried using numerous \ to
escape the \xb1.
I also tried replacing all non numeric characters that are part of a
number-character string but I could not make that work. The idea was replace
all non-number characters in a "word" that is made up of numbers followed by
numbers.
I then split the line at the commas so in the current thinking I need the
commas for the split. How do I deal with the hPa±? When I print it out it
looks like it is a hexadecimal escape character (\xb1) but I am note sure
how to deal with this.
Any ideas?

[Tutor] Dates and databases, and blobs and Python.
Hi,
Just a quick query. I want to store dates and work with them in my
SQLite database.
There's no specific need for any calculations to done on one side or
another (i.e. it's a single user database).
I googled how to work with dates in SQL, and I got one like this -
SELECT * FROM totp
WHERE wk BETWEEN '1980/05/20'
AND '1980/05/26'
as an example of finding a range for a date. I'm not too sure about
how SQL works with dates (and times for that matter), so I'm tempted
to stick to what I know and just store dates/times as strings in the
db, and then use them to create datetime objects when needed.
i.e.
>>>cx.execute('select date, time from foo where c_id = 10')
>>>dat = cx.next()
>>>tim = cx.next()
>>>print dat, time
2005-12-31, 7:00
>>>splitD = dat.split('-')
>>>splitT = time.split(':')
>>>intD = [int(i) for item in splitD]
>>>intT = [int(i) for item in splitT]
>>> theDateTime = datetime.datetime(intD[0], intD[1], intD[2], intT[0], intT[1])
Although working with dates like that doesn't seem that flash either.
Alternatively, I was thinking of storing the actual datetime object in
the database (this is a blob I believe?), and that's a whole new
kettle of fish.
So far I've tried this -
>>> import datetime
>>> theDT = datetime.datetime(2004, 12, 31, 7, 30)
>>> print theDT
2004-12-31 07:30:00
>>> import sqlite
>>> c = sqlite.connect('foo.db')
>>> cx = c.cursor()
>>> import pickle
>>> j = pickle.dumps(theDT)
>>> cx.execute('insert into bob values(%s)', j)
>>> cx.execute('select A from bob')
>>> q = cx.next()
>>> print q
("cdatetime\ndatetime\np0\n(S'\\x07\\xd4\\x0c\\x1f\\x07\\x1e\\x00\\x00\\x00\\x00'\np1\ntp2\nRp3\n.",)
>>> w = pickle.loads(q[0])
>>> print w
2004-12-31 07:30:00
So, it works, but I'm not too sure. I tend to have a random approach
to using the standard library, as I don't fully understand what all of
the modules do.
This provokes the following questions -
1. Should I be using StringIO for this instead?
2. Would my retrieved unpickled datetime object still work if datetime
hadn't been imported?
3. Is there a better way to work with blobs and Python?
And then there's the overall question -
What would be the least fiddly & least error prone way of working with
dates and times? Python or SQL?
Thank you for your time.
