get the total number of code lines in python?

Question

I just wanted to know if there is a way to get all the lines of code written and then assign it to a variable and finally print it in python?. I'm trying to make a toy benchmark and I need to calculate the productivity

Answer 1

Here is a short routine to count the number of lines in any text file, not just a program module. This is very simplistic--it counts all lines, including blank lines and comments. Continuation lines are treated as separate lines, multiple statements on one line are counted as only one line, etc. I used an f-string for simplicity, so this requires Python 3.6 or above. The print line can easily be modified for other versions of Python.

def count_lines(filename):
    with open(filename) as f:
        cnt = sum(1 for line in f)
        print(f'There are {cnt} lines in {filename}')
