在大型文本文件的某个百分位数中打印一行

def print_line_in_percentile(file_path, percentile):
    # 读取文本文件并计算行数
    with open(file_path, 'r') as file:
        lines = file.readlines()
        total_lines = len(lines)

    # 根据百分位数计算目标行数
    target_line = int(total_lines * percentile / 100)

    # 重新遍历文本文件，找到目标行并打印
    with open(file_path, 'r') as file:
        for i, line in enumerate(file):
            if i == target_line:
                print(line)
                break

# 示例用法
file_path = 'path/to/your/file.txt'
percentile = 50
print_line_in_percentile(file_path, percentile)
