Python RegEx Split – re.split()

from re import split

# 'W+' denotes Non-Alphanumeric Characters or group of characters Upon finding ',' or whitespace ' ', the split(), splits the string from that point
print(split('W+', 'Words, words , Words'))
print(split('W+', "Word's words Words"))

# Here ':', ' ' ,',' are not AlphaNumeric thus, the point where splitting occurs
print(split('W+', 'On 5th Jan 1999, at 11:02 AM'))

# 'd+' denotes Numeric Characters or group of characters Splitting occurs at '5', '1999','11', '02' only
print(split('d+', 'On 5th Jan 1999, at 11:02 AM'))

python re split

>>> re.split(r'W+', 'Words, words, words.')
['Words', 'words', 'words', '']
>>> re.split(r'(W+)', 'Words, words, words.')
['Words', ', ', 'words', ', ', 'words', '.', '']
>>> re.split(r'W+', 'Words, words, words.', 1)
['Words', 'words, words.']
>>> re.split('[a-f]+', '0a3B9', flags=re.IGNORECASE)
['0', '3', '9']

Python re.split()

import re

string = 'Twelve:12 Eighty nine:89.'
pattern = 'd+'

result = re.split(pattern, string) 
print(result)

# Output: ['Twelve:', ' Eighty nine:', '.']

re python split()

s_comma = 'one,two,three,four,five'

print(s_comma.split(','))
# ['one', 'two', 'three', 'four', 'five']

print(s_comma.split('three'))
# ['one,two,', ',four,five']

Python RegEx Split – re.split() Syntax

re.split(pattern, string, maxsplit=0, flags=0)

re.split

import re

text = "python is, an easy;language; to, learn."
print(re.split("[;,] ", text))

re.split

import re
text = "python is, an easy;language; to, learn."
separators = "; ", ", "


def custom_split(sepr_list, str_to_split):
    # create regular expression dynamically
    regular_exp = '|'.join(map(re.escape, sepr_list))
    return re.split(regular_exp, str_to_split)


print(custom_split(separators, text))
