Hey guys, in this blog we will see a Python Program to Get the Line Count of a File.
The content of the file my_file.txt is

Example 1: Using a for loop
def file_len(fname): with open(fname) as f: for i, l in enumerate(f): pass return i + 1 print(file_len("my_file.txt"))
- Here we have just opened the file and used enumerate to count the number of lines in the file and then returned i+1.
- We just started a for-loop and we are not performing any function in it.
Example 2: Using list comprehension
num_of_lines = sum(1 for l in open('my_file.txt')) print(num_of_lines)
- Here also opened the file and calculated the number of lines.
- The first line in the code says that for each found line in the code, add a 1 in our tuple and will create a result like sum(1,1,1) which is equal to 3.
