如何删除列表中的文件路径，只显示文本文件？

import os

def is_text_file(file_path):
    text_extensions = ['.txt', '.csv', '.log']  # 可以根据需要添加其他文本文件的扩展名
    file_extension = os.path.splitext(file_path)[1]
    return file_extension in text_extensions

def filter_text_files(file_paths):
    text_files = []
    for file_path in file_paths:
        if is_text_file(file_path):
            text_files.append(file_path)
    return text_files

# 示例用法
file_paths = ['path/to/file1.txt', 'path/to/file2.jpg', 'path/to/file3.csv']
text_files = filter_text_files(file_paths)
print(text_files)
