python中局部變量的定義

1/ 局部變量的定義

    在所有函數內定義的變量叫局部變量,在函數外的都是全局變量.

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 是全部變量,因為它沒有在函數中定義,故不能算局部變量.
