Scratch

OK, this makes no sense....

This code:

import http.client
import time
userchoice = str(input("Select a website: "))
load = http.client.HTTPConnection(userchoice)
load.request("GET", "/")
r1 = load.getresponse()
print(r1.read())
time.sleep (5000)

It works like a dream in IDLE, but gives me a flurry of traceback errors that go by too fast to read in regular Python. Any help, please?

Works perfectly for me (or would, if it didn't keep keep printing the HTML of the websites); no error message.

Hey max, I was wondering if you knew anything about the "Pickle" way of saving files in python. In my program, it's supposed to save a list, but when it does the pickle.dump(), I get an error saying

Error wrote:

Traceback (most recent call last):
  File "Z:\python_programs\Textgame1", line 124, in <module>
    pickle.dump(savelist, Name + "textventure.txt")
  File "C:\Python26\lib\pickle.py", line 1362, in dump
    Pickler(file, protocol).dump(obj)
  File "C:\Python26\lib\pickle.py", line 203, in __init__
    self.write = file.write
AttributeError: 'str' object has no attribute 'write'

Can you help? Much thanky.

Hm.  It would help to know what your program was, but I can do my best.  First of all, start the file by writing 'import picke'.  Second of all, never do '.write', I think.  Always '.dump'.  Third, you can only pickle lists.  Fourth, always end the file name of pickles in '.dat'.  Without knowledge of what you actually have, that's all I can do.

Thanks. I did import pickle, but I was trying to save it as a .txt. Thanks!
EDIT: Not helping. Do I have an outdated version or something? I'm using 2.6.

Yea, just found that out. 

  Python is easy for me.  I like the modules though, they make is so organised!

1.  Why use objects to indirectly access methods instead of just directly accessing static methods?

Because it uses less memory and allows run-time flexibility of defining functions, not like when it gets compiled.

4.  How does Python/PyGame make .exe files instead of .py files (imagine something like WoW or CoD where you can just right-click on the program and choose 'edit in IDLE' to hack the entire game).

5.  How do you make a project using multiple programming languages in the same project (I heard about a few things that did like Ruby and Perl or something like that some years back)?

JYthon for Java and this for C/C++ are ways. This is also very helpful.

PS I love this site!

Anyone?

Nope, even if you compile it to .exe with py2exe (the python IDE itself doesn't have a compiler linked), you can't really embed it anywhere, unless you put it up for download.


To the OP, looks like you have all your questions but I can tell you Python is an easy language and you shouldn't take it too seriously if you're planning to actually learn programming. Also you're not all that much proficient if you haven't even learned classes yet, that's like saying I know C++ when all of my programs are just gotos and if statements.

thx. and if you were talking to me, im just learning.

I should try Python, ...maybe

I actually do a good bit of C++.  I'm just not particularly fond of classes.  I feel like functions seem more logical to use, unless you're writing in Java (I do a tiny bit of that) or something, where classes are mandatory.

A large deal of programming is about efficiency, and classes definitely add to that. I bet you know that classes can contain functions, too? I didn't use that much object-oriented programming as I was starting out, but it just became more simple when my programs reached over 1500 lines of code.

Yeah, I know.  I just don't get what makes it better to say, for example, 'g.say()' instead of 'say()'.  But yeah, I guess so.

Who builds classes just for a say()? Your example of classes is like this example of functions - "who needs funcprint(this) instead of cout  < this?

Yes, I know, I know.  I was just using that as an example, from a classic Ruby Hello World program (

class Greeter
def initialize( name )
@name = name.capitalize
end
def say
puts "Hello #{@name}!"
end
end
g = Greeter.new( "world" )
g.say

in case you were wondering).
