Run multiple find and replaces in Python (on every file in the folder and sub-folder)
Use the glob module to get a list of *.html files.
I have a folder (courses) with sub-folders and a random number of files. I want to run multiple search and replaces on those random files. Is it possible to do a wild card search for .html and have the replaces run on every html file ? 
Search and replaces:
1) "</b>" to "</strong>"
2) "</a>" to "</h>"
3) "<p>" to "</p>"
Also all these replaces have to be run on every file in the folder and sub-folders.
Thank you so much
