My code lists the files and directory under a folder and if we want to read
the file it uses the function cat.
But the function cat(get_file) is not working , any suggetions?
Here is my code:
#!/usr/bin/python
import os
import sys
import commands
#import cat
def listdir(s):
try:

Python doesn't _have_ variables. Python has names and objects.

Actually, it's better to use the fully qualified name "file_1.a".
Using "import *" brings in everything in the other module, which o

I need to use global var across files/modules:

Here above 'a' is not imported from file_1
Better yet, write them out as constants if they're referenced more
than once. In that case, if the planet gets knocked into a new orbital
and rotational pattern, you can update accordingly if you,
civilization, and Python all still exist.

In general I always prefer the pure functional approach. But you are
right, if it is too costly, one has to weigh the pros and contras.
Here's some stupid trick I came up with after reading this thread. It's
of very limited use, of course and I
import calendar
print 366 if calendar.isleap(2003) else 365

i want to know how many days in one year,
import time
import datetime
d1= datetime.datetime(2003, 1, 1)
d2=datetime.datetime(2003, 21, 31)
print (d2-d1).days+1
i can get there are 365 days in the 2003,
is there other way,better way to calculate ?
