python中局部变量的定义

1/ 局部变量的定义

    在所有函数内定义的变量叫局部变量,在函数外的都是全局变量.

for guessTaken in range(1,2):
    print(\'Take a guess\')
    guess = int(input())

    if(guess < secretNumber):
        print(\'your guess too low\')
    elif(guess > secretNumber):
        print(\'your guess too high\')
    else:
        break




if(guess == secretNumber):
    print(\'oK\')
else:
    print(\'fail\')

一定注意,上面描述的guess 是全部变量,因为它没有在函数中定义,故不能算局部变量.
