Question

在处理我的程序时，我遇到了一个问题，即菜单选项1中存储的信息没有传输到菜单选项2.如您所见，它在菜单1中正确存储。当它返回到菜单选项2时，它就像从未进入选项1一样。

更新＃1：我有一些建议是了解范围？从我可以告诉程序，即使我在每个定义中输入了返回，程序也没有将数据传递给它的父程序。

#Must be able to store at least 4 grades
#Each class can have up to 6 tests and 8 hw's
#Weighted 40%*testavg 40% hw average attendance is 20%
#User must be able to input a minimum grade warning
#after each test the your program must calculate the students average and issue warning if necessary

##Define the Modules##
import math

def menu (a): #2nd thing to happen 
    menuend = 'a'
    while menuend not in 'e':
        menuend = raw_input("Type anything other then 'e' to continue:\n")
        print "What would you like to do ?"
        menudo = 0
        print "1 - Enter Courses\n2 - Select Course to Edit\n3 - Save File\n4 - Load File\n5 - Exit\n"
        menudo = input("Enter Selection:")
        if (menudo == 1):
            menuchck = 0
            menuchck = raw_input("\nYou have entered #1 (y/n)?:\n")
            if menuchck in ["Yes","yes","y","Y"]:
                x = m1()
            else:

##Menu Options##

###User Input Section###

raw_input("This is the end, my only friend the end")

Answer 1

在do == 1案例中的if-elif块中，您编写m1()，但在最后一种情况下，您编写x=m1()。你应该把后者放在任何地方（通过键入m1()你只运行该函数，但不要将返回的x存储在任何地方。）

顺便说一句，你可以使用if chck in ["Yes","yes","Y","y"]:

来避免这种if-elif混淆
