Hi,
I am trying to search a string through files in a directory -
however while Python script works on it and writes a log - I want
to present the user with count of number of strings found. So it
should increment for each string found.
How do I implement it?
If I use a print() within a if condition statement - and execute
the script in terminal - for each find, the print() prints in new
line instead of a constantly incrementing counter.

In Python 3, you can specify what to do at the end of the print.
Normally it prints a newline, but you can make it print nothing at the
end, leaving the cursor just after the last thing printed:
>>> def counter(x):
... for i in range(x):
... print("\rProgress .............. %s" % i, end="")
... sys.stdout.flush()
... time.sleep(1)
...
>>> counter(5)
The "\r" moves the cursor back to the start of the line so that it
overwrites what was printed last time.
