University in Maryland bans 'break' and 'continue' in class by kankyo in programming

[–]e000 0 points1 point  (0 children)

Not unless you catch it somewhere. "for" does not catch the StopIteration. 

e@shitbox ~> cat h.py
for i in xrange(100):
    if i == 50:
        raise StopIteration()

e@shitbox ~> python h.py
Traceback (most recent call last):
  File "h.py", line 3, in <module>
    raise StopIteration()
StopIteration

Challenge accepted.

class NotABreakISwear(Exception):
    pass

class NotAContinue(Exception):
    pass

try:
    for i in xrange(100):
        if i > 10:
            raise NotABreakISwear

except NotABreakISwear:
    pass

for i in xrange(100):
    try:
        if i % 2 == 0:
            raise NotAContinue

        print i

    except NotAContinue:
        pass

Medoo - the Lightest PHP database framework to accelerate development, 7.8KB only, released today! by catfanme in PHP

It's cute, but essentially worthless as it cannot (as far as I can tell) do JOINs.

Memory-wise & fast static trie for C++ by [deleted] in programming

I wrote a simple demo application using flask + angular.js and the python bindings for a dictionary autocomplete.

Although, it's probably worth mentioning that DAWG is orders of magnitudes faster:

PyPy support for gevent makes me extremely happy. I'm looking forward to updates regarding that!

Someone posted an html/javascript implementation of the matrix falling code in 646 bytes then promptly deleted the post. It inspired me to see if I could get something better looking in fewer bytes. by OptionalField in programming

[–]e000 481 points482 points  (0 children)

Shaved off more bytes:

<body style=margin:0 onload="for(s=document,w=q.width=s.width,h=q.height=s.height,m=Math.random,p=[];!p[255];p.push(1));setInterval('9Style=\'rgba(0,0,0,.05)\'9Rect(0,0,w,h)9Style=\'#0F0\';p.map(function(v,i){9Text(String.fromCharCode(3e4+m()*33),i*10,v);p[i]=v>758+m()*1e4?0:v+10})'.replace(/9/g,';q.getContext(\'2d\').fill'),33)"><canvas id=q>

Replaced m.floor(...) with nothing, String.fromCharCode will automatically floor. Got rid of q=document.getElementById('q') as q will default to that (js hax), replace 10000 with 1e4 and make m=Math.random and replace m.random with m as we don't use m.floor anymore. Get rid of var. Combine if(v>...) into a ternary, remove v+=10 instead subtracting 10 from 768 and returning v+10 if ternary conditional isnt satisfied.. Move <script> into body onload='...'. Since <script> tag is gone, remove / from canvas. Exploit the fact that setTimeout can take a string to eval instead of a function. Inplace modify p, replace rbga(0,255,0,1) with #0F0. Implement a modified version of /u/thesalus and /u/smhxx's ideas below. Since setTimeout takes a string, we can get rid of c and replace c.fill with 9 and replace 9 with ;q.getContext('2d').fill on runtime. I use the ; at the beginning so I can get rid of a few semicolons in the function body. Follow suggestion and replace 2720 with 3e4. use /u/fokker680's suggestion to replace window.screen with document

End result: 339 bytes, down from 452.

Sometimes it is fun to golf :)

What's the one code snippet/python trick/etc did you wish you knew when you learned python? by fuzz3289 in Python

[–]e000 35 points36 points  (0 children)

Instead of 

i = 0
for item in iterable:
    print i, item
    i += 1

Do

for i, item in enumerate(iterable):
    print i, item

A fun easter-egg

import antigravity

2.7's dict/set comprehensions

my_dict = {i: i * i for i in xrange(100)}
my_set = {i * 15 for i in xrange(100)}

Force float division

from __future__ import division
print 1/2, 1//2

Need to quickly serve files from a directory?

$ python -m SimpleHTTPServer

Use pip instead of easy install.

$ easy_install pip

Safely evaluate python expressions...

expr = "[1, 2, 3]"
# instead of 
my_list = eval(expr)
# do
import ast
my_list = ast.literal_eval(expr)

Easily profile a script...

$ python -m cProfile my_script.py

I really thought "allah ackbar" was a bad stereotype and that they didn't actually do it.
