名称'f'未定义（Pycharm IDE）

Question

Pycharm一直说f是未定义的，即使它是。 我做错了什么？

def Main():

    f = open("C:\Users\Donna\Desktop\myfile.txt","w")

for i in range(4):
    f.write=(raw_input("Enter a word here")+'\n')
if __name__ =="__main__":
 Main()

Answer 1

def Main():

    f = open("C:\Users\Donna\Desktop\myfile.txt","w")

    for i in range(4):
        f.write=(raw_input("Enter a word here")+'\n')

缩进有问题
