variable regex python

MyDir = os.getcwd().split(os.sep)[-1]

command = re.search(r"(MyDir)", body).group(1)

etc

hi guys,

am trying to have a python script (on windows) search my outlook email body for certain words using regex

that works fine, coupled with the rest of the script (not shown)

but the minute i want it to search for a variable, ie MyDir it does nothing when i fire off an email to myself with the word: documents in the body of the email (documents, being the directory the script is located on this occasion; though should populate the variable with whatever top level directory the script is being run from)

now i have read and seen that re.escape is a method to consider, and have copied lots of different variations, and examples and adapted it to my scenario, but none have worked, i have built the regex as a string also, still no joy

is there anything in my MyDir "variable" that is throwing the regex search off?

am stumped, its my first python script, so am sure am doing something wrong - or maybe i cant use os.getcwd().split(os.sep)[-1] inside regex and have it not look at the variable but the literal string!

thanks for any help, as i have read through similar regex+variable posts on here but havent worked for me

:)

Try:

command = re.search("(" + re.escape(MyDir) + ")", body).group(1)

You searching for the string MyDir not the variable MyDir. You could use str.format

command = re.search(r"({})".format(MyDir), body).group(1)
