How to split a string by string in Python?
How to split a string by string in Python? For example,
"a string separated by space" =>
["a", "string", "separated", "by", "space"]
and
"a,string,separated,by,comma" =>
["a", "string", "separated", "by", "comma"]
Python’s string.split() standard library function, if provided a separator, will split the string by the separator, for example
>>> str2 = "a,string,separated,by,,,comma"
>>> str2.split(",")
['a', 'string', 'separated', 'by', '', '', 'comma']The remaining problem is to handle the empty strings caused by the consecutive separators. We can filter away the empty strings to solve this.
[s for s in str2.split(",") if s != ""]or
list(filter(lambda s: s != "", str2.split(",")))Then we get
['a', 'string', 'separated', 'by', 'comma']
