Question

我有这个简化的代码（我正在处理的代码实际上更大）...

def My_Age()
    Age = input ("What is your age")

def Message()
    print ("Your age is:", Age)

# Main program
Message()

我的问题是如何在消息函数中显示Age中的值？

Answer 1

别忘了＆＃39;：＆＃39;用于功能

def My_Age():
    Age = input ("What is your age? ")
    return Age

def Message():
    print ("Your age is: " + str(My_Age()))

# Main program
Message()

# Output:
# What is your age? 15
# Your age is: 15

使用参数

编辑：

def My_Age():
    Age = input ("What is your age? ")
    return Age

def Message(age):
    print ("Your age is: " + str(age))

# Main program
Age = My_Age()
Message(Age)

Answer 2

def My_Age():
    # No need a variable
    return(input("What is your age? "))

def Message():
    print ("Your age is: {}".format(My_Age()))

# Main program
if (__name__ == '__main__'):
    Message()

最好在主程序之前使用此if (__name__ == '__main__'):语句，以便可以从其他函数调用此脚本中的函数。看一下这个 What does if __name__ == "__main__": do?

Answer 3

您可以使用全局变量：

def My_Age():

        global Age
        Age = input ("What is your age")
def Message():

        My_Age()
        print ("Your age is: "+ Age)
Message()

Answer 4

你确定你一直在寻找吗？

def My_Age()
    Age = input ("What is your age")
    return Age

def Message()
    print ("Your age is:", My_Age())

# Main program
Message()

Python传递变量
