字符升序python_检查字符串的字符是否按字母顺序升序,并且其上升是均匀间隔的python...

>>> from itertools import product

>>> from string import lowercase

>>> a="abc"

>>> any(a in lowercase[i::j+1] for i,j in product(range(26),repeat=2))

True

>>> b="ceg"

>>> any(b in lowercase[i::j+1] for i,j in product(range(26),repeat=2))

True

>>> c="longer"

>>> any(c in string.lowercase[i::j+1] for i,j in product(range(26),repeat=2))

False

>>> d="bdfhj"

>>> any(d in string.lowercase[i::j+1] for i,j in product(range(26),repeat=2))

True

没有必要使用产品,而且这样做效率更高一些

>>> any(a in string.lowercase[i::j+1] for i in range(26) for j in range(26-i))

True
