How can I check the length of the python code?

Question

Is there a method to check the length of the CURRENT full code?

Similar to this:

#The file is the current code, not an another
file = open("main.py", "r")
length_in_lines = file.linelength()
length_in_characters = file.chars()

If you know a similar method to solve this or fix the errors, on the code thank you :D

Try the following:

file = open("main.py", "r")
length_in_lines = len(file.readlines())
file.seek(0)
length_in_char = len(file.read())

readlines() reads all the lines of the file in a list.

read() reads the whole file in a string.

The len() function returns the length of the argument.

This would not work for the file's number of characters. The file's pointer would be at the end of the file after reading the lines. It is necessary to `seek` the file's pointer to the beginning again. – Sherlock Bourne May 27 '21 at 14:25
Good catch. Fixed. – ahmadjanan May 27 '21 at 14:27

You can try this:

with open('script.py') as file:
    lines = len(file.readlines())
    file.seek(0)
    chars = len(file.read())

print('Number of lines: {}'.format(lines))
print('Number of chars: {}'.format(chars))

You would first get a list with all the lines, and getting the list's length (so, the number of lines), and then you would read the whole file as a string and count all the characters in it.

Use the code below for reading characters and lines of code.

file = open("main.py", "r")

print(len(file.readlines()))
print(len(file.read()))
