Splitting a string can sometimes give empty strings returned in the Python split() method.
For example, how Python split method to return list with empty space.
str1 = '/segment/segment/'.split('/') print(str1)
More generally, to remove empty strings returned in
split() results, you may want to look at the
f = filter(None, '/segment/segment/'.split('/')) s_all = list(f) print(s_all)
Output: [‘segment’, ‘segment’]
How to Python split ignore the empty example
Python simple example code. As per upper code, it was only one type of problem but in real-time there can be more.
Method 1: Example Remove all Empty Strings From the List using List Comprehension
import re s = '--hello-world_how are\tyou-----------today\t' words = re.split('[-_\s]+', s) print(words) words = [x for x in words if x != ''] print(words)
Method 2: Example Remove all Empty Strings From the List using filter()
import re s = '--hello-world_how are\tyou-----------today\t' words = re.split('[-_\s]+', s) words = list(filter(bool, words)) print(words)
Method 3: Example use re.findall() Instead
import re s = '--hello-world_how are\tyou-----------today\t' words = re.findall('([^-_\s]+)', s) print(words)
