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']
