Numbers passed as command line arguments in python not interpreted as integers
argv, python
Solution
You can convert the arguments to integers using int()
import sys
a = int(sys.argv[1]) b = int(sys.argv[2])
print a, b
print a+b
input: `python mySum.py 100 200`
output:
100 200
300
Problem
I am familiar with C, and have started experimenting in python. My question is regarding the `sys.argv` command. I've read it is used for a command line interpreter, but when trying to execute a simple program I don't get the results I expect. Code: ``` import sys a = sys.argv[1] b = sys.argv[2] print a, b print a+b ``` Input: ``` python mySum.py 100 200 ``` Output: ``` 100 200 100200 ``` When I add the two arguments they are concatenated instead of the two values being added together. It seems that the values are being taken as strings. How can I interpret them as numerics?
