Function to take input as string, input parameter to function

[David Aghan]

Ok, so I am almost done with this question:
Write and test a function to take as input a list of strings (each of which
represents a number) and to return a list of numeric values. For example, if
the input to the function is [“67”, “8”,”75”] and return [67,8,75]. The input
should be as a parameter to the function.

here is the code I have written:

def func( num1, *numtuple):
    print num1
    for num in numtuple:
        print num

it works fine except for the fact that the input HAS to be as a string. Any help would be great because I am stumped.

Cheers

The instructions require the function argument to be a list of strings as in

['1','2','3']

This can be done two ways.

def f(*args):
    # Accept a variable number of arguments
    pass

def f(strList):
    # Accept a single argument
    pass

Your function must return a list of numbers. This can be done several ways, but you must use the return statement as in

def f(*args):
    # Calculate somevalue
    return somevalue

Assuming the numbers are all integers, here are some examples:

>>> strList = ['1','2','3']
>>> map(int, strList)
[1, 2, 3]
>>> [int(n) for n in strList]
[1, 2, 3]
>>> result = []
>>> for n in strList:
... 	result.append(int(n))
... 	
>>> result
[1, 2, 3]
>>>
