【Python】【翻转字符串】

要求：在Python环境下用尽可能多的方法反转字符串,例如将s = "abcdef"反转成 "fedcba"
【1】：使用字符串切片

result = s[::-1]

l = list(s)
l.reverse()
result = "".join(l)

【3】：使用reduce

result = reduce(lambda x,y:y+x,s)

def fun(s):
if len(s)<1:
return s
return func(s[1:])+[0]
result = func(s)

【5】：使用栈

def func(s):
l = list(s) #模拟全部入栈
result = ""
while len(1)>0:
result += 1.pop() #模拟出栈
return result
result = func(s)

【6】：for循环

def func(s):
result = ""
max_index = len(s)-1
for index,value in enumerate(s):
result += s[max_index-index]
return result
result = func(s)
