Python remove or replace a certain part in several text files

 Sometimes you need to remove or replace a certain part in several text files and if that is 20 or 100 or completely 1000 templates that is a whole load of work. How can you do it with python? That goes without saying that it's a weird case and normally you only have 1 or 2 template files but imagine if you have a static static generator and no CMS then you may occasionally find yourself in a situation where you will need such a script. To avoid such situations, keep content separate from tempaltes.

NOTE: commit and test how it works first without opening file to write. 

 You can see correct representation of text in debugger and copy there.

        print("----- In file ------")
        print(infile)
        content = open(infile, "r").read()
        content = replace(content)
        print(content)
        #outfile = open(infile, "w")
        content = content.encode('utf-8')
        content = content.decode('utf-8')
        #outfile.write(content)
        #outfile.close()
