Python string contains word

Use if…in the statement to check string contains the word in Python.

if word in mystring: 
   print('success')

but keep in mind that this matches a sequence of characters, not necessarily a whole word – for example, 'word' in 'swordsmith' is True. If you only want to match whole words, you ought to use regular expressions:

Python string contains the word

A simple example code checks if a word is in a string in Python. If you want to do a case-insensitive search you can normalize strings using the lower() or upper() methods like this:

sentence = 'There are more trees on Earth than stars in the Milky Way galaxy'
word = 'milky'

if word in sentence.lower():
    print('Word found.')
