Python regex split without empty string

Python regex split without empty string

You can use the re.split() function in Python with a regular expression to split a string without including empty strings in the result. To achieve this, you can use a regular expression that matches the delimiters while also using a positive lookahead assertion to ensure that the delimiter is followed by a non-empty string. Here's an example:

import re # Sample string with delimiters text = "one,two,,three,four," # Split the string using a regex pattern result = re.split(r',(?=[^,])', text) # Output the result print(result)

In this example, the regular expression r',(?=[^,])' is used for splitting. It looks for commas , followed by a character that is not a comma [^,]. The (?= ...) is a positive lookahead assertion that ensures that the comma is followed by a non-empty string.

The result will be a list without empty strings:

['one', 'two', 'three', 'four', '']

As you can see, the empty strings resulting from consecutive delimiters are excluded from the final result.
