I am using the same code that Kenneth is using but not getting the same o/p. I am using pycharm to run my code.

Code:

import re

name_file = open("names.txt", encoding="utf-8")
data = name_file.read()
name_file.close()
# print(data)
# last_name = r'Love'
# first_name = r'Kenneth'
print(re.match(r'Love', data))
print(re.search(r'Kenneth', data))

o/p:

C:\Users\Kishore\AppData\Local\Programs\Python\Python35-32\python.exe C:/Users/Kishore/PycharmProjects/RegularExpression/address_book.py

None
<_sre.SRE_Match object; span=(7, 14), match='Kenneth'>

Process finished with exit code 0

Hi Kishore, can you add what output you were expecting?

The match returns None since the entire data does not match "Love" exactly.

Did you intend to use groups by adding parens to mark group?

>>> print(re.search(r'(Love)', string).groups())
('Love',)
>>>

re.match only matches the beginning of a string. re.search matches anywhere in the string.
