我正在为我的班级写一个简短的程序而且我被困在最后一部分.当我运行程序时,一切都正常运行,直到我到达代码的末尾,我试图将两个单独函数的成本相乘以定义另一个函数.我怎么能纠正这个？
这是完整的代码:
def main():
wall_space = float(input('Enter amount of wall space in square feet: '))
gallon_price = float(input('Enter the cost of paint per gallon: '))
rate_factor = wall_space / 115
total_gallons(rate_factor, 1)
total_labor_cost(rate_factor, 8)
total_gal_cost(rate_factor, gallon_price)
total_hourly_cost(rate_factor, 20)
total_cost(total_hourly_cost, total_gal_cost)
print()
def total_gallons(rate1, rate2):
result = rate1 * rate2
print('The number of gallons of required is: ', result)
print()
def total_labor_cost(rate1, rate2):
result = rate1 * rate2
print('The hours of labor required are: ', result)
print()
def total_gal_cost(rate1, rate2):
result …
