Exact keyword match in string

I know this question has been asked almost hundred times in stack overflow but after doing lot of search and not finding my answer, I am asking this question.

I am looking to search exact word from strings something like below. 

'svm_midrangedb_nonprod:svm_midrangedb_nonprod_root'
'svm_midrangedb_prod:svm_midrangedb_prod_root'

I want to search only for 'prod' but getting both 'prod' and 'nonprod' in output.

Here is the code I am using:

re.search(r"\wprod\w", in_volumes.json()[i]['name'].split(":")[2].lower())

You have to make rules to not match nonprod but match prod.

For example, maybe you can make it so that if there's n infront of prod, you exclude it like this: [^n]prod\w.

Or maybe some data has n infront of prod and you want to keep it. Then, you want to exclude if there's non infront of prod like this: \w*(?<!non)prod\w*.

It really depends on the rest of your data and see what kind of rules you can make/apply to them to get your desired data.

It's normal because your regular expression tell that you want a string containing "prod", in order to solve that very easily you can do the same thing you did but like follow re.search(r"\w_prod\w", in_volumes.json()[i]['name'].split(":")[2].lower()) I just add a _ character existing in your targeted string
