Python:拆分由给定对象类型分隔的字符串

Question

如何分割分隔符是 Python 数据类型的字符串？

例如:

str_to_split = 'a1b2c'
str_to_split.split(int)
# ['a','b','c']

Answer 1

您可以使用 re.split() :

>>> import re
>>> thingToSplit = 'a1b2c'
>>> re.split('\d+', thingToSplit)
['a', 'b', 'c']

或者，申请 isdigit()检查:

>>> [item for item in thingToSplit if not item.isdigit()]
['a', 'b', 'c']
