I want to know how to delete strings after a keyword in python

I will get lines in a txt file

What method could I use to do this.

For example:

“I have a book to read.”

I want to delete all words after “book”.

Answer 1

To remove everything after the first “book” including “book” itself:

s = "I have a book to read."
print(s.partition("book")[0])

To preserve the word “book”:

print(''.join(s.partition("book")[:2]))

Both work whether “book” present in the string or not.
