Here is a simple program to get the file extension in Python. import os # unpacking the tuple file_name, file_extension = os.path.splitext("/Users/pankaj/abc.txt") print(file_name) print(file_extension) print(os.path.splitext("/Users/pankaj/.bashrc")) print(os.path.splitext("/Users/...
上述代码中,我们使用os.path.splitext()函数来获取文件扩展名,并将其存储在file_extension变量中。 步骤二:判断文件扩展名是否为有效的Python扩展名 接下来,我们需要判断文件扩展名是否为有效的Python扩展名。在Python中,有效的扩展名是.py。 defcheck_python_extension(file_extension):iffile_extension=='.py':retu...
