I'm trying to loop through list of arguments passed by the prompt in calling the function in python I want to get the sys.argv[1] as integer not string

this is the code i wrote in the function

x=[1,2,3,4,5]
for n in x:
    print sys.argv[1] * n

if i called the previous function with 5 i receive

    5
    55
    555
    5555
    55555

how can i receive

5
25
125
625

any ideas what can be the solution

import sys
x=[1,2,3,45]
try:
    for n in x:
        print int(sys.argv[1]) * n
except IndexError:
    print "No argument were passed to the program"

Output:

simply by doing this

x=[1,2,3,45]
for n in x:
    print int(sys.argv[1]) * n

but be careful this solution will blow up if you pass anything that can't be casted into a string or if you are not passing anything. So you probably want to catch any exceptions with a try and except block.
