这是我的代码

def main():
    # This code reads in data.txt and loads it into an array
    # Array will be used to add friends, remove and list
    # when we quit, we ll overwrite original friends.txt with
    # contents 

    print"Welcome to the program"

    print "Enter the correct number"
    print "Hockey fan 1, basketball fan 2, cricket fan 3"
    choice = input("Select an option")

    while choice!=3:
        if choice==1:
            addString = raw_input("Who is your favorite player??")
            print "I love Kessel"
        elif choice==2:
            remInt = raw_input("Do you think that the Cavaliers will continue ther loosing ways?")
            print "I think they can beat the Clippers"
        else:
             "You must choose a Number (1,2 or 3)"
    print "Cricket is a great sport"
    choice = input("Select an option")



    inFile = open( data.txt , r )
    listNumbers = []
    for numbers in inFile:
        listNumbers.append(numbers)
        print numbers
    inFile.close()

if __name__ == "__main__":
    main() # will call the  main  function only when you execute this from the command line.

Answer 1

添加：

if __name__ == "__main__":
    main()

到您的脚本（一直向左缩进；不是作为main（）函数的一部分）。

Answer 2

添加：

if __name__ == "__main__":
    main()

到文件末尾

Answer 3

您应该尝试以下操作

if __name__ == "__main__":
    main()

完成后，您应该从命令行如下调用程序（假设您使用的是Linux/Mac）

python <your_prog>

Also it will be helpful if you give the exact error that you are getting. Also make sure that all the indentation is correct.
