def last_n_lines(f, n):

        :param f: file object
        :param n: number of lines to return
        :return: list of strings
        """
        lines = []
        for i in range(n):
            lines.append(f.readline())
        return lines

# Enter the file
file = open("test.txt", "r")

# Enter the number of lines to read
n = 3

# Calling the function
lines = last_n_lines(file, n)

# Printing the lines
