python print 列出所有

要使用Python的print函数列出特定文件夹下的所有文件名，你可以使用以下代码：

import os

folder_path = 'E:\机器学习\Python数学建模算法与应用课件'
file_names = [filename for filename in os.listdir(folder_path) if filename.endswith(('.pptx','.txt'))]
for name in file_names:
    print(name)

这段代码首先导入了os模块，然后使用listdir函数获取指定文件夹下的所有文件名，并使用列表推导式过滤出只以'.pptx'和'.txt'结尾的文件名。最后使用print函数逐行输出文件名。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
