Python中反转字符串的常见方法小结

string = 'hello world'
reversed_string = string[::-1]
print(reversed_string)  # 输出: dlrow olleh

string = 'a string'
reversed_string = ''.join(reversed(string))
print(reversed_string)  # 输出: gnirts a

def reverse_string(string):
    new_string = ''
    for i in range(len(string) - 1, -1, -1):
        new_string += string[i]
    return new_string

string = 'python'
reversed_string = reverse_string(string)
print(reversed_string)  # 输出: nohtyp

import grapheme

def reverse_graphemes(string):
    g = list(grapheme.graphemes(string))
    return ''.join(g[::-1])

string = "👈🏾👆"
reversed_string = reverse_graphemes(string)
print(reversed_string)  # 输出: 👆👈🏾

def reversed_string(a_string):
    return a_string[::-1]

def reverse_string_readable_answer(string):
    return ''.join(reversed(string))

def reverse_a_string_slowly(a_string):
    new_string = ''
    index = len(a_string)
    while index:
        index -= 1
        new_string += a_string[index]
    return new_string

    g = list(grapheme.graphemes(string))
    return ''.join(g[::-1])
