Your task is to create a python script (single .py file) which will read the file "fileSpec" searching for the string "from" and, when found, replacing it with "to".

The invocation of the script must be as follows:

python modify.py fileSpec from to where, modify.py is the name of your script

fileSpec is the name of the file to be modified (smb.txt)

from is the text to be searched for (be sure to enclose any white space in quotes.

to is the text the searched text is to be replaced with.
