将函数的答案赋值给变量？(in python 2.4.4)
Assigning the answer of a function to a variable?(in python 2.4.4)
def BSformula(num1):
"""my formula"""
(num1 - 2.0) * (2 / num1)
def main():
number = input("value")
answer = BSformula(number)
print(answer)
main()
当我 运行 它总是打印 "None"
>>>
value: 6
None
>>>
如何将答案分配给变量？
或者我只能在 def BSformula 中打印它吗？？
只需使用关键字 return.
