Python变量名称.错误

Question

在Python中，我正在编写一个程序来计算类(class)的成绩，考虑到类(class)作业的类型、每个类(class)的权重和分数。这是代码:

def get_initial_input():
    try:
        tests = int(input("How many tests are there? "))   #get number of tests
    except ValueError:
        print("Invalid number")
        get_initial_input()
    class_weight()

def class_weight():
    print("What is the weighted percent of the class?")
    if tests > 0:     #<-- this is where the error is
        try:
            tests_weight = float(input("Tests: "))
        except ValueError:
            print("Invalid weight")
            class_weight()

def main():
    get_initial_input()

main()

每当我运行它时，我都会收到 builtins.NameError 发生消息:名称“tests”未定义 错误。该变量似乎是在程序的前面定义的，但由于某种原因似乎没有正确定义。任何帮助将不胜感激!

def get_initial_input():
    try:
        tests = int(input("How many tests are there? "))   #get number of tests
    except ValueError:
        print("Invalid number")
        get_initial_input()
    class_weight(tests)

def class_weight(tests):
    print("What is the weighted percent of the class?")
    if tests > 0:     #<-- this is where the error is
        try:
            tests_weight = float(input("Tests: "))
        except ValueError:
            print("Invalid weight")
            class_weight()

def main():
    get_initial_input()

main()

只要通过测试就可以了。
