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.
