I get the following message when I try to run the below program: builtins.NameError: global name 'gallons' is not defined

def main():
    square_feet = float(input("Enter the square feet of the wall that is to be painted: "))
    gallons = (square_feet/115)
    paint = float(input("Enter the cost of paint per gallons: "))
    labor = (gallons * 8 * 20)
    price_paint = (paint + gallons)
    hours = (square_feet/14.37)
    total_cost = (labor + price_paint)
    charges()
def charges():
    print ("The number of gallons of paint is", gallons)
    print ("The number of hours of labor is",hours)
    print ("The cost of the paint is",price_paint)
    print ("The cost for labor will be",labor)
    print ("The total cost for the paint job is", total_cost)
main()

The definition of gallons is local to function main() and not in the namespace of function charges(). For more information about Python's scope rules see Python documentation 9.2. Python Scopes and Namespaces.

Okay, how do you do it in 2 functions then?

Create global variables with the global statement or pass the values to function charges() as arguments.
