How do you Python get the size of the file?

You can calculate the size manually using the file object’s seek and tell methods, though it is less preferred.

def get_file_size(file_path):
    with open(file_path, 'rb') as file:
        file.seek(0, 2)  # Move cursor to the end
        size = file.tell()
    return size

file_size = get_file_size('myfile.bin')
print(f"File size: {file_size} bytes")

This method mimics the process you provided but is encapsulated in a reusable function.
