6. Split a String and Keep Delimiters To split a string while keeping the delimiters, you can use there.split()function with capturing groups. importre text="apple,banana;orange.grape"fruits=re.split("([,;.]) ",text)print(fruits)# Output: ['apple', ',', 'banana', ';', 'orange'...
将字符串拆分为最多2个元素的列表:txt = "apple#banana#cherry#orange" #将maxsplit参数设置为1,将返回一个包含2个元素的列表 x = txt.split("#", 1) print(x) 'apple', 'banana#cherry#orange' 参考: python 3 string split method examples python 3 split string into list...

Below we'll define another decorator that splits the sentence into a list. We'll then apply the uppercase_decorator and split_string decorator to a single function. import functools def split_string(function): @functools.wraps(function) def wrapper(): func = function() splitted_string = func...
