如何在python中读取文本文件的任意行？

def read_specific_line(file_path, line_number):
    with open(file_path, 'r') as file:
        lines = file.readlines()
        if line_number < len(lines):
            return lines[line_number]
        else:
            return "Line number out of range."

# 示例用法
file_path = 'path/to/your/file.txt'
line_number = 2
specific_line = read_specific_line(file_path, line_number)
print(specific_line)
