可能重复:
Python 是否具有用于字符串自然排序的内置函数?

python中是否有相当于php的natcasesort()的函数?

import re

def atoi(text):
    return int(text) if text.isdigit() else text.lower()

def natural_keys(text):
    '''
    alist.sort(key=natural_keys) sorts in human order

    (See Toothy's implementation in the comments)
    '''    
    return [ atoi(c) for c in re.split('(\d+)', text) ]

names = ('IMG0.png', 'img12.png', 'img10.png', 'img2.png', 'img1.png', 'IMG3.png')

标准排序:

print(sorted(names))
# ['IMG0.png', 'IMG3.png', 'img1.png', 'img10.png', 'img12.png', 'img2.png']

自然顺序排序(不区分大小写):

print(sorted(names, key = natural_keys))
# ['IMG0.png', 'img1.png', 'img2.png', 'IMG3.png', 'img10.png', 'img12.png']
