Regex with python

Question

Hi people!
Can anyone tell me how would I use regex in python. For exemple I want to check if a word is in a dictionary that has a word on every line.
If ‘hone’ in open(‘dictionary.txt’).read():
Print(‘found!’)

This would print ‘found!’ even if it finds word ‘phone’ or ‘honey’ in dictionary

As a linux guy I know how it would be done with grep and regex

grep ‘^word$’ dictionary.txt

How can I do that in python?
Thanks!

Answer 1

I wrote a code on some RegEx examples quite a time ago. Perhaps you'll make a use of it.

Answer 2

If you have a string that looks like:

st = “phone\nhoney”

You can do:

lis = st.split(“\n”)

It returns a list of strings: “phone” and “honey”. Then you can search the list, and you won’t have that problem.

Answer 5

Lets say I have a string ‘one’ and I want to check if that string is in a dictionary. But I want it to follow these rules when checking:
A line must start with that string
A line must end with that string

Correct:
(Start of line)one(end of line)

Wrong:
(Start of line)phone(end of line

In both these cases the example i have gave you will find it
