arly of for-loops,
but not list comprehensions. The whole point is with a list comp,
you're forced to iterate over the entire sequence, even if you know
that you're done and would like to exit.
Take a look at itertools.takewhile!
result = [i%2 for i in itertools.takewhile(lamda x:i< 10, seq)]

han by exhaustion, I
cannot anticipate what will be found
What I am looking for is some help to get started, either with
explaining the implementation of one of the modules with respect to my
format, or with an approach that I could use from the base library.
What is your ultimate goal?

t understand urllib.urlopen(). Could some kind soul explain what I'm
doing wrong.
1) put a / after .com
2) encode it (in this case that means replace blanks with %20)
x=urllib.urlopen("http://maps.google.com/?q=18%20Tadlock%20Place%20Woodland%20CA";)

translate to Python fairly easily!
What do we do at steps 4ff if the line does not end in "yes" or "no"?
If you have not written any code make a stab at it. You could start by
asking "how in Python does one":
open a file
ending in 'yes'
line = data.read().strip()
if line:
if line.endswith('yes'):
state = 1
else state = 6
elif state == 1:
# code for state i
# more states
elif state == 6:
data.close()
break
To simplify things I'd create a function to read and s
() instead of invoking
this constructor directly. file is more suited to type testing (for
example, writing "isinstance(f, file)").
Unfortunately no explanation as to WHY open is preferred. I have long
wondered that myself.
Perhaps someone with more enlightenment can t

In the relentless pursuit of terseness:
>>> class L(list):
... def add(self, end, *item):self[-end:-end] = item
>>> a=[4,6,'word',3,9]
>>> result=L()
>>> [result.add(
o this:
[4, 6, 'word', 3, 9]
should be:
['word', 3, 4, 6, 9]
Why not:
>>> sorted(lst, key=lambda x: (0, x) if isinstance(x, str) else (1, x))
['word', 3, 4, 6, 9]
Again in the relentless pursuit of terseness:
sorted(a, key=lambda x: (isinstance(x, int)
x27; is a relative path. It looks in the current directory.
Obviously that file is not in the current directory. So you must provide
the complete path.
That is no longer a Python issue!
The path to the desktop depends on OS and username!
I suggest you put the file in a different
101 - 200 of 1317 matches
