Well i'm learning Python cuz' i think is an awesome and powerful language like C++, perl or C# but is really really easy at same time. I'm using JetBrains' Pycharm and when i define a function it ask me to add a "Documentation String Stub" when i click yes it adds somethin like this:
"""
"""
so the full code of the function is something like this:
def otherFunction(h, w):
"""
"""
hello = h
world = w
full_word = h + ' ' + w
return full_word
I would like to know what these (""" """) symbols means, Thanks.
Ps.Data: Sorry for my bad english :D
This is a question I have wondered about for quite some time, yet I have never found a suitable solution. If I run a script and I come across, let's say an IndexError, python prints the line, location and quick description of the error and exits. Is it possible to automatically start pdb when an error is encountered? I am not against having an extra import statement at the top of the file, nor a few extra lines of code.
I need to change some characters that are not ASCII to '_'.
For example,
Tannh‰user - Tann_huser
If I use regular expression with Python, how can I do this?
Is there better way to do this not using RE?
I have an unknown number of functions in my python script (well, it is known, but not constant) that start with site_...
I was wondering if there's a way to go through all of these functions in some main function that calls for them.
something like:
foreach function_that_has_site_ as coolfunc
if coolfunc(blabla,yada) == true:
return coolfunc(blabla,yada)
so it would go through them all until it gets something that's true.
thanks!
I am trying really hard to make a sliding frame containing widgets in tkinter in python. There is this frame inside a big window with different widgets. And as soon as i click on the next button on that frame the frame should slowly slide towards the left and vanish ultimately. As soon as it vanishes, i want new frame with widgets to come sliding towards right.
What should i do?
Anticipating your suggestions and ideas.
Does anybody know any module in Python that computes the best bipartite matching?
I have tried the following two:
munkres
hungarian
However, in my case, I have to deal with non-complete graph (i.e., there might not be an edge between two nodes), and therefore, there might not be a match if the node has no edge. The above two packages seem not to be able to deal with this.
Any advice?
hello.
What is the pythonic way to test if there is a tuple starting with another tuple in collection? actually, I am really after the index of match, but I can probably figure out from test example
for example:
c = ((0,1),(2,3))
# (0,) should match first element, (3,)should match no element
I should add my python is 2.4 and/or 2.5
thanks
How can I split a line in Python at a non-printing ascii character (such as the long minus sign hex 0x97 , Octal 227)?
I won't need the character itself. The information after it will be saved as a variable.
I need a way to determine the space remaining on a disk volume using python on linux, Windows and OS X. I'm currently parsing the output of the various system calls (df, dir) to accomplish this - is there a better way?
I'm new in python and I'm having some issues doing a simple thing.
I've an array (or list as it's said in pyton) like this:
list = [ 'NICE dog' , 'blue FLOWER' , 'GOOD cat' , 'YELLOW caw']
As you see each element of this array contains some words. These words is both lowercase and uppercase.
How I can delete from this array each lowercase words?
For example I'd like to have as result this list:
list = [ 'NICE' , 'FLOWER' , 'GOOD' , 'YELLOW']
Hi all
I am a newbie to the python. Can I unhash, or rather how can I unhash a value. I am using std hash() function. What I would like to do is to first hash a value send it somewhere and then unhash it as such:
#process X
hashedVal = hash(someVal)
#send n receive in process Y
someVal = unhash(hashedVal)
#for example print it
print someVal
Thx in advance
I'm trying to work with sockets and I have such problem
In code example:
setsockopt(socket.SOL_SOCKET,IN.SO_BINDTODEVICE,self.listen_address+'\0')
I have error
AttributeError: 'module' object has no attribute 'SO_BINDTODEVICE'
On Linux machine this attribute is OK but on FreeBSD trere are no any SO_* attributes in module IN. What port should I install to resolve this problem on FreeBDS machine?
Python versions on Linux tested:
2.5.4 and 2.6.4;
on FreeBSD:
2.5.5
I can't find anything about this module in my book, and googling keyword IN looks like seamless ...
Im using python to access a MySQL database and im getting a unknown column in field due to quotes not being around the variable.
code below:
cur = x.cnx.cursor()
cur.execute('insert into tempPDBcode (PDBcode) values (%s);' % (s))
rows = cur.fetchall()
How do i manually insert double or single quotes around the value of s?
I've trying using str() and manually concatenating quotes around s but it still doesn't work.
The sql statement works fine iv double and triple check my sql query.
In Python I can use the iterkeys() method to iterate over the keys of a dictionary. For example:
mydict = {'a': [3,5,6,43,3,6,3,],
'b': [87,65,3,45,7,8],
'c': [34,57,8,9,9,2],}
for k in mydict.iterkeys():
print k
gives me:
a
c
b
How can I do something similar in Javascript?
Good day chaps.
I'm interested in learning how to invert (make a negative of) an image using the python image libary module.
I cannot however, use the ImageOps function 'invert.' I need another solution, using the RGB values. I've searched and tried to no avail. Thanks for any help :)
I'm writing a shell for a project of mine, which by design parses commands that looks like this:
COMMAND_NAME ARG1="Long Value" ARG2=123 [email protected]
My problem is that Python's command line parsing libraries (getopt and optparse) forces me to use '-' or '--' in front of the arguments. This behavior doesn't match my requirements.
Any ideas how can this be solved? Any existing library for this?
I am looking to setup a automated screen scraper that will run on Google app engine using python. I want it to scrape the site and put the specified results into a Entity in app engine. I am looking for some directions on what to use. I have seen beautifulsoup but wonder if people could recommend anything else that could run on Google App engine.
I am trying to get python to make noise when certain things happen. Preferably, i would like to play music of some kind, however some kind of distinctive beeping would be sufficient, like an electronic timer going off. I have thus far only been able to make the system speaker chime using pywin32's Beep, however this simply does not have the volume for my application.
Any ideas on how I can do this?
I want to break a Python string into its characters.
sequenceOfAlphabets = list( string.uppercase )
works.
However, why does not
sequenceOfAlphabets = re.split( '.', string.uppercase )
work?
All I get are empty, albeit expected count of elements
How can I log into my Launchpad account in a python script? Any sample code would be appreciated.
The login url is https://launchpad.net/+login and then redirect to something like https://login.launchpad.net/fJLVSRbxPfKTpVDr/+decide
Thanks in advance!
Hi, I have an application that starts several threads using
gobject.timeout_add(delay, function)
Now in my function I want to test and set on some variable, e.g.
def function(self):
if flag == True:
flag = False
doSomething()
Now to make this threadsafe, I would have to lock the function using some mutex lock.
Is this possible with Gtk? Or can I use the Python Lock objects from threading?
I have two lists: one contains a set of x points, the other contains y points. Python somehow manages to mix the x points up, or the user could. I'd need to sort them by lowest to highest, and move the y points to follow their x correspondants. They are in two separate lists.. how do I do it?
Hi folks,
