Split a string into 2 in Python
提问by Kiwie Teoh
Is there a way to split a string into 2 equal halves without using a loop in Python?
有没有办法在不使用 Python 循环的情况下将字符串分成 2 个相等的一半？
采纳答案by Senthil Kumaran
firstpart, secondpart = string[:len(string)/2], string[len(string)/2:]
回答by lalli
a,b = given_str[:len(given_str)/2], given_str[len(given_str)/2:]
回答by J. Lernou
Another possible approach is to use divmod. rem is used to append the middle character to the front (if odd).
另一种可能的方法是使用 divmod。rem 用于将中间字符附加到前面（如果是奇数）。
def split(s):
half, rem = divmod(len(s), 2)
return s[:half + rem], s[half + rem:]
frontA, backA = split('abcde')

In Python 3:
If you want something like
madam => ma dam
maam => ma am
在 Python 3 中：
如果你想要像
madam => ma这样的东西d上午
MAAM =>毫安时
first_half = s[0:len(s)//2]
second_half = s[len(s)//2 if len(s)%2 == 0 else ((len(s)//2)+1):]

minor correction the above solution for below string will throw an error
小更正以下字符串的上述解决方案将引发错误
string = '1116833058840293381'
firstpart, secondpart = string[:len(string)/2], string[len(string)/2:]
you can do an int(len(string)/2)to get the correct answer.
你可以做一个int(len(string)/2)来得到正确的答案。
firstpart, secondpart = string[:int(len(string)/2)], string[int(len(string)/2):]
firstpart, secondpart = string[:int(len(string)/2)], string[int(len(string)/2):]
