In Perl it is possible to do something like this (I hope the syntax is right...):
$string =~ m/lalala(I want this part)lalala/; $whatIWant = $1; I want to do the same in Python and get the text inside the parenthesis in a string like $1.

It returns a Boolean (either True or False ). To check if a string contains a substring in Python using the in operator, we simply invoke it on the superstring: fullstring = "StackAbuse" substring = "tack" if substring in fullstring: print("Found!") else: print("Not found!")
sub() method will replace all pattern occurrences in the target string. By setting the count=1 inside a re. sub() we can replace only the first occurrence of a pattern in the target string with another string. Set the count value to the number of replacements you want to perform.
If you want to get parts by name you can also do this:
>>> m = re.match(r"(?P<first_name>\w+) (?P<last_name>\w+)", "Malcom Reynolds") >>> m.groupdict() {'first_name': 'Malcom', 'last_name': 'Reynolds'} The example was taken from the re docs

>>> import re >>> p = re.compile("lalala(I want this part)lalala") >>> p.match("lalalaI want this partlalala").group(1) 'I want this part' If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
