The split method of the re module
The split method of the re module splits a string and returns the resulting list. The first parameter is a regular expression. The second parameter specifies the string we want to split. The third optional parameter specifies the maximum number of parts to split. The fourth optional parameter specifies flags for additional regular expression settings.
Syntax
import re
re.split(regular expression, string, [max. number of parts], [flags bunting])
Example
Let's split the line at the hyphen:
txt = 'aaa-bbb-123 456'
res = re.split('-', txt)
print(res)
Result of code execution:
['aaa', 'bbb', '123 456']
Example
Now let's split the line at the hyphen twice:
txt = 'aaa-bbb-123-456'
res = re.split('-', txt, 2)
print(res)
As can be seen from the code execution result, the string was split at the hyphen only into two parts. And the third part of the string included its remainder:
['aaa', 'bbb', '123-456']
