Python Program to Get Line Count of a File

The line count of a file is the number of lines that the file contains. In computing, a line is a sequence of characters terminated by a newline character, which marks the end of the line. The line count of a file can be used to determine the size of the file or to analyze its contents.

Python Code : #

The Below Python program gets the line count of a file:

filename = input("Enter the filename: ")

# Open the file in read mode
with open(filename, 'r') as file:
    # Use the readlines() method to get a list of all the lines
    lines = file.readlines()

# Get the total number of lines in the file
num_lines = len(lines)

# Print the line count
print("There are", num_lines, "lines in", filename)

This program first asks the user to enter the filename. Then it opens the file in read mode using a with statement, which ensures that the file is automatically closed when we’re done with it.

Next, the program uses the readlines() method to get a list of all the lines in the file. The readlines() method reads the entire file and returns a list where each element is a line from the file.

Finally, the program uses the len() function to get the number of lines in the list, and prints the line count along with the filename.
