If I do this in the python interpreter...

>>> args = ['1996','2000']
>>> print args
['1996', '2000']
>>> intArgs = [int(x) for x in args]
>>> print intArgs
[1996, 2000]
>>> a = intArgs[1] + 1
>>> print a
2001

...everything is fine.


But if I do this in a '.py' file....

args = getopt.getopt(sys.argv[1:], '')

intArgs = [int(x) for x in args]

...I get this error...

Traceback (most recent call last):
  File "./assignment6.py", line 21, in  <module>
    intArgs = [int(x) for x in args]
TypeError: int() argument must be a string or a number, not 'list'

I guess my question is how can I convert a list item to an integer? I have some experience with C++ and Java (in an educational setting) but I am completely new to Python

Seems some arguments are lists (if you read the error). What arguments are you passing?

Also, check out map function.

str_list = ["1", "2", "3"]
int_list = map(int, str_list)
