在python中从函数中传递值

Question

I am trying to get my head around python. This is a snippet of code where I want to have the user input an option in a function and then use that input in another function(s). This tells me 'myInput' is not defined.

def main():          
    myInput = input("Enter a number ")
#     This is the main function that will be the primary executuable function - the start of the program

    return(myInput)


if __name__ == '__main__':
    main()
#


print (myInput)

Answer 1

Function main returns the user's input, so try this:

if __name__ == '__main__':
    myInput = main()
