NameError：全局名称“ myExample2”未定义＃模块
问题内容：
这是我的example.py文件：
from myimport import *
def main():
myimport2 = myimport(10)
myimport2.myExample()
if __name__ == "__main__":
main()
这是myimport.py文件：
class myClass:
def __init__(self, number):
self.number = number
def myExample(self):
result = myExample2(self.number) - self.number
print(result)
def myExample2(num):
return num*num
运行example.py文件时，出现以下错误：
NameError: global name 'myExample2' is not defined
我该如何解决？
问题答案：
这是您的代码的简单修复。
from myimport import myClass #import the class you needed
def main():
myClassInstance = myClass(10) #Create an instance of that class
myClassInstance.myExample()
if __name__ == "__main__":
main()
和myimport.py：
class myClass:
def __init__(self, number):
self.number = number
def myExample(self):
result = self.myExample2(self.number) - self.number
print(result)
def myExample2(self, num): #the instance object is always needed
#as the first argument in a class method
return num*num
