Question

This is my script:

fruit  = "apple"
phrase = "I like eating " + fruit + "s."

def say_fruit(fruit):
    print phrase

say_fruit('orange')

I’m trying to get say_fruit to use the string given inside the phrase variable, which actually uses the variable already assigned before to it (apple). How can I achieve this?

Answer 1

In your code, phrase is bound to a string when the module loads and is never changed. You need to be dynamic, like this:

def phrase(fruit):
    return "I like eating " + fruit + "s."

def say_fruit(fruit):
    print phrase(fruit)

Globals are just a bad idea that will haunt you in the future. Resist the temptation to use them.
