How to count lines with new line character?

Counting the number of lines in a text file can be a useful task in various applications such as text processing, data analysis, and programming. One way to count the number of lines in a text file is to use the newline character, also known as the "line feed" or "end of line" character.

In most operating systems, the newline character is represented by the combination of two characters: a carriage return (CR) and a line feed (LF). The CR is represented by the code '\r' and the LF is represented by the code '\n'. In Windows, the newline character is represented by the combination of a CR and LF, '\r\n', while in Unix and Linux systems it is represented by only the LF, '\n'.

Here is an example of how you can count the number of lines in a text file using Python:

with open("file.txt", "r") as f: lines = f.readlines() line_count = len(lines) print("Number of lines:", line_count)

This code uses the built-in open() function to open a text file, and the readlines() method to read the file and return a list of lines. The len() function is then used to count the number of elements in the list, which represents the number of lines in the file.

Another way to count the lines in a text file is to use the splitlines() method, which splits a string by the newline character and returns a list of lines.

you can count number of line with an online tool called Line counter.

In summary, counting the number of lines in a text file can be done by using the newline character, also known as the "line feed" or "end of line" character. The newline character is represented by the combination of two characters: a carriage return (CR) and a line feed (LF). By using the method readlines() or splitlines(), we can count the lines in a file.
