首先,我们需要检查路径是否存在。为此,我们可以使用os.path.exists()函数来检查路径是否有效。下面是相应的代码段: importosdefcheck_path_valid(path):ifos.path.exists(path):print("路径有效")else:print("路径无效") 1. 2. 3. 4. 5. 6. 7. 接下来,我们需要获取文件名。使用os.path.basename()函数可...
这个主要归功于配置的系统环境变量PATH,当我们在命令行中运行程序时,系统会根据PATH配置的路径列表依次查寻是否有可执行文件python(在windows中,省略了后缀.exe),当查寻到该文件时,执行该文件; 如果在所有路径列表中都查找不到,就会报报错:'python' 不是内部或外部命令,也不是可运行的程序或批处理文件。 test.py...

If you need some more advanced functionality, then this is where you should go. But for 90% of the time you're dealing with directories and files, theosoros.pathmodules should have you covered. Although, one valid use-case might be when you're doing multiple tests on the same file and...
