You could say:

logfile.write('Total matches lines: ' + str(len(matched_lines)))

Or:

logfile.write('Total matches lines: {}'.format(len(matched_lines)))

Turn it into one argument, such as with the newish format strings:

logfile.write(f'Total Matched lines : {len(matched_lines)}\n')

Or, if you're running a version before where this facility was added (3.6, I think), one of the following:

logfile.write('Total Matched lines : {}\n'.format(len(matched_lines)))
logfile.write('Total Matched lines : ' + str(len(matched_lines)) + '\n')

Aside: I've added a newline since you're writing to a log file (most likely textual) and write does not do so. Feel free to ignore the \n if you've made the decision to not write it on an individual line.

Try:

logfile.write('Total Matched lines : {}'.format(len(matched_lines)))

or:

logfile.write('Total Matched lines : %d' % len(matched_lines))
