python 三种方法实现字符串倒序显示

import pytest
@pytest.fixture()
def init(request):
    str_1 = 'hello 8888'
　　 print('第一种方法')
　　 str_5 = str_1[::-1]
　　 print('第二种方法')

    str_6 = list(str_1)
    str_6.reverse()



    print("替换前的字符串",str_1)
    print("第一种倒序排列的字符串",str_5)
    print("第二种倒序排列的字符串",''.join(str_6))

@pytest.fixture()

    str_1 = 'hhhhh kkkk gggg'
    c = len(str_1) - 1
    str_7 = []
    while (c > 0):
        str_7.append(str_1[c])
        c -= 1
    print('第三种倒序排列后的字符串', ''.join(str_7))
