In this post we will be creating a Python script that will count the number of lines present within a text file, to do this we will be using a for loop that will iterate each line within the file.
See the snippet of code below where we count 1 for every line found within the specified text file.
num_lines = sum(1 for line in open('file.txt')) print(num_lines)
Below is a snippet of our text file which we’ll be using for this example.
With the above our script will output the following as the number of lines in the text file.
