Python Program to calculate number of lines in a text file
'''Description:
1. The program will ask the user to enter the file name.
2. Initially the counter is set to zero.
3. The program fetches each line from the file and simultaneously increments the counter.
4. It prints the final count.
5. It will also consider the blank lines of the text file. If you dont want to include the blank lines you need to use strip function.
6. Time module has been imported to calculate the execution time.
