[问题求助] 这个Python正则怎么写啊？

ab,cd,gf,jh,ht,kh ===> [ab],[cd],[gf],[jh],[ht],[kh]

ivor

re.sub(r"[a-z]{2}","[\g<0>]","ab,cd,gf,jh,ht,kh")
复制代码

or

re.sub(r'([a-z]{2})',r'[\1]',"ab,cd,gf,jh,ht,kh")
复制代码

Gin_Q

>>> for i in re.findall('[a-z]{2}',a):
	b.append('[' + i + ']')

	
>>> b
['[ab]', '[cd]', '[gf]', '[jh]', '[ht]', '[kh]']
>>> 
>>> a
'ab,cd,gf,jh,ht,kh'
>>>
