Strings are objects in Python. They have a method named
split that lets you
split the string.
For example, here is a string containing commas that we split:
>>> string = "red,blue,green" >>> string.split(",") ['red', 'blue', 'green']
In general, the
.split() method takes a string as its argument, and returns
a list of strings.
You can split by a longer pattern:
>>> string = "this - also - works" >>> string.split(" - ") ['this', 'also', 'works']
If you use
split without giving any arguments, then the string will be split
by any whitespace characters, such as spaces and tabs:
>>> string = "this is a\tstring" >>> string.split() ['this', 'is', 'a', 'string']
The second argument to split is the maximum number of times to split:
>>> sentence = "hello world how are you" >>> sentence.split(" ", 2) ['hello', 'world', 'how are you']
You can use the
rsplit method to split starting at the right instead of at
>>> sentence = "hello world how are you" >>> sentence.rsplit(" ", 2) ['hello world how', 'are', 'you']
join method is the opposite of split. For example:
>>> sentence = "hello world how are you" >>> words = sentence.split(" ") >>> reconstructed = " ".join(words) >>> print(reconstructed) hello world how are you
