I need to collect a couple of integers from a user, but I want to make
sure that I actually get integers. I tried this, but subsequent calls
to the function don't update variable. I'm not sure this is terribly
clear - here's the code:
num_of_articles = 0
num_of_reviewers = 0
def getinput(variable,prompt):
"""
Get the input by prompting the user and collecting the response - if it is
a non-integer, try again.
"""
variable = 0
variable = raw_input(prompt)
try:
int(variable)
return variable
except ValueError:
print("We need an integer (number) here.")
getinput(variable,prompt)
num_of_articles = getinput(num_of_articles,"Enter number of articles: ")
num_of_reviewers = getinput(num_of_reviewers,"Enter number of reviewers: ")
print(num_of_articles)
print(num_of_reviewers)
This works fine if I put in good input, but not if I pass in a bad
value. Can anyone show me where I have gone astray? Thanks.
