如何在python中使用随机数并将字符串连接到字符串random_number的次数

Question

如何在python 3中使用随机数并将字符串连接到另一个字符串random_number次数????

import random
fave_word = 'hello' + 'world'

def randomword(fave_word : str) -> str:
    '''Return something'''
    rand_num = random.randint(0,3)
    for i in range(rand_num):
        fave_word += 'Bob'
print(fave_word)

Answer 1

您需要返回已创建的字符串。或者您可以使用global，但我not recommend that approach：

>>> import random
>>> fave_word = 'hello' + 'world'
>>>
>>> def random_word(word : str) -> str:
...     '''Return something'''
...     rand_num = random.randint(0,3)
...     for i in range(rand_num):
...         word += 'Bob'
...     return word
...
>>> print(random_word(fave_word))
helloworldBobBobBob
>>> print(random_word(fave_word))
helloworld
>>> print(random_word(fave_word))
helloworldBobBob
