为了优化这段代码，有几个方面可以考虑：

1. 减少文件读写操作：在 `extract_data` 函数中，每个文件都会被打开和读取三次。可以考虑在打开文件后，将所有数据一次性读取，并存储在一个列表中，以减少文件读写操作。

2. 使用列表推导式：在 `extract_data` 函数中，可以使用列表推导式来简化代码，减少重复的代码行数。

3. 将绘图部分与数据处理部分分离：将数据处理和绘图的功能拆分为两个独立的函数，这样可以提高代码的可读性和可维护性。

下面是优化后的代码示例：

import os
import matplotlib.pyplot as plt
import sys


def extract_data(rbp_name):
    data = []
    subfolders = ['lncRNA', 'miRNA', 'mRNA', 'snoRNA', 'snRNA', 'tRNA']
    for subfolder in subfolders:
        folder_path = os.path.join(rbp_name, subfolder, '3.normalization')
        ctrl_file = os.path.join(folder_path, f'Ctrl_{subfolder}_rpm.txt')
        rep1_file = os.path.join(folder_path, f'rep1_{subfolder}_rpm.txt')
        rep2_file = os.path.join(folder_path, f'rep2_{subfolder}_rpm.txt')

        with open(ctrl_file, 'r') as f:
            ctrl_data = [line.strip().split('\t')[1] for line in f]

        with open(rep1_file, 'r') as f:
            rep1_data = [line.strip().split('\t')[1] for line in f]

        with open(rep2_file, 'r') as f:
            rep2_data = [line.strip().split('\t')[1] for line in f]

        data.append(ctrl_data)
        data.append(rep1_data)
        data.append(rep2_data)

    return data

def create_boxplot(rbp_name, data):
    fig, ax = plt.subplots()
    ax.boxplot(data)

    subfolders = ['lncRNA', 'miRNA', 'mRNA', 'snoRNA', 'snRNA', 'tRNA']
    x_labels = [f'Ctrl_{subfolder}', f'rep1_{subfolder}', f'rep2_{subfolder}'] * len(subfolders)
    ax.set_xticklabels(x_labels, rotation=45)

    plt.savefig(os.path.join(rbp_name, f'{rbp_name}_boxplot.pdf'))
    plt.close()

if __name__ == "__main__":
    rbp_name = sys.argv[1]

    # 提取数据
    data = extract_data(rbp_name)

    # 创建箱线图
    create_boxplot(rbp_name, data)

这样，代码更加简洁，同时减少了文件读写操作，提高了效率。
