Re: [Tutor] triple-nested for loop not working
I have not checked the rest of your code, but: for line in seqalign: for i in len(finalmotif_seqs): # for item in finalmotif_seqs: for i in len(finalmotif_annot): # for item in finalmotif_annot: I see two problems here: 1. You are using the same loop variable in both loops here. That's likely to cause problems 2. You let the loops go over len(finalmotif_seqs). len(finalmotif_seqs) is a number, and you can't loop over a number. You should use the form as you write after the #. -- André Engels, andreeng...@gmail.com ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
[Tutor] assigning a variable a value
Hi,
I am learning python and I am trying to write a simple guess the number
game. I wrote the program in the IDLE, and I set the variable tries=1 to keep
up
with the number of tries it takes to guess the number, but when I try to run
the
program it gives the error message improper syntax and highlights the word
tries. So, I assigned the variable tries the value 1 in the python shell
window
and it works fine there. Can you tell me why it won't work in the program? A
copy of my code is below for clarification.
#Guess My Number
#
#The computer picks a random number between 1 and 100
#The player tries to guess it and the computer lets
#the player know if the guess is too high, too low, or correct
import random
print('Welcome to Guess My Number!')
print('\nI\'m thinking of a number between 1 and 100.')
print('Try and guess the number in as few turns as possible.')
#set initial values
num = random.randint(1,100)
guess = int(input('Take a guess: ')
tries = 1
while guess != num:
if guess num:
print('Too high. Guess lower.')
else:
print('Too low. Guess higher.')
guess=input('Take another guess: ')
tries += 1
print('You guessed it. The number was',num)
print('Congratulations, You guessed the correct answer.'
print('It only took you',tries,'tries.')
input('\n\nPress enter to exit.')
I highlighted the problem in red.
Thanks for any help.

If the parser tells you there's a syntax error, it is often in the line it shows, but also often in the line preceding that. In this case, it is the latter: You have two opening brackets there, but only one closing bracket. -- André Engels, andreeng...@gmail.com ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

First please post the actual error in full, not just a rough summary.
Pythopn error messages are very informative and helpful once
you know how to read them. However, in this case its not needed.
The thing to remember with errors, especially syntax errors, is that
Python reports them where it identifies the problem. But that may
be a line or so later than where the actual error occurs. That is
what happened here. Look at the guess= line and count the
parentheses
num = random.randint(1,100)
guess = int(input('Take a guess: ')
tries = 1
print('Too low. Guess higher.')
guess=input('Take another guess: ')
you probably need to convert to int() here too...

Re: [Tutor] Titles from a web page
louis leichtnam l.leicht...@gmail.com wrote I'm trying to write a program that looks in a webpage in find the titles of a subsection of the page: Can you help me out? I tried using regular expression but I keep hitting walls and I don't know what to do... Regular expressions are the wrong tool for parsing HTML unless you are searching for something very simple. There is an html parser in the Python standard library (*) that you can use if the HTML is reasonably well formed. If its sloppy you would be better with something like BeautifulSoup or lxml. If the page is written in XHTML then you could also use the element tree module which is designed for XML parsing. (*)In fact there are two! - htmllib and HTMLParser. The former is more powerful but more complex. Some brief examples can be found in my tutor here: http://www.alan-g.me.uk/tutor/tutwebc.htm Note, the topic is not complete, the last few sections are placeholders only...

What I actually want is 100 2x2 arrays and then mutliply them individually. Can anyone help me with that? As Alan said, you'll likely get good help on the numpy listserv, but I think this might be what you want, although I'm not sure it's the tersest way to express it: # Swap axes twice on A and B to make them (100, 2, 2) A_new = np.swapaxes(np.swapaxes(A, 0, 2), 1, 2) B_new = np.swapaxes(np.swapaxes(B, 0, 2), 1, 2) # Multiply the 2x2 arrays together using list comprehension C = np.array([np.dot(a, b) for a, b in zip(A_new, B_new)]) print C I'm certain there is a more clever way (ie. some function within numpy) to do that last part. matt ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Reading elements in a file
string.capwords(s[, sep]) So capwords is a little bit different but you can use a combination of split() and title() to do some of it. Title() will work for the default case, but if you split on non-whitespace then you will need to manually use split(). 'test test test'.title() 'Test Test Test' This is the only one I think you cannot do from the str object. (Well, not in Python2.

[Tutor] dictionary

Re: [Tutor] dictionary
Supposing your dictionary like this: dict={1:'My name is X',2:'My name is x
y z',3: 'i am X'}
You can use len(list) :
dict={1:'My name is X',2:'My name is x y z',3: 'i am X'}
for values in dict.values():
... if len(values.split(' '))3:
...print values
My name is X
My name is x y z
