Regex with python

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 ā€˜hone’ in open(ā€˜dictionary.txt’).read(): Print(ā€˜found!’) This would print ā€˜found!’ even if it finds word ā€˜phone’ or ā€˜honey’ in dictionary As a linux guy I know how it would be done with grep and regex grep ā€˜^word$’ dictionary.txt How can I do that in python? Thanks!

I wrote a code on some RegEx examples quite a time ago. Perhaps you'll make a use of it. https://code.sololearn.com/c40z8B7tOdCN/?ref=app

If you have a string that looks like: st = ā€œphone\nhoneyā€ You can do: lis = st.split(ā€œ\nā€) It returns a list of strings: ā€œphoneā€ and ā€œhoneyā€. Then you can search the list, and you won’t have that problem.

Lets say I have a string ā€˜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
