用echo命令来显示PATH变量,用$给变量名加前缀以向shell表示我们需要这个变量的 值。可以把你选择的目录添加到PATH变量 中去——这可以通过运行PATH=$PATH:/home/swaroop/mydir完成,其中"/home/swaroop/ mydir"是我想要添加到PATH变量中的目录 基本的数据类型是数和字符串 ...
上述代码块中,判断文件/目录是否存在,用的是同一个方法exists()。如果文件/目录存在,则返回True;否则,返回False。 此外,针对文件,还可以使用is_file()方法;针对目录,还可以使用is_dir()方法。文件(或目录)若存在,则返回True;否则,返回False。 代码语言:javascript ...

Now you can use the different methods is_file(), is_dir(), and exists() on the Path object:if my_file.is_file(): # file exists if my_file.is_dir(): # directory exists if my_file.exists(): # file or directory exists
The p.exists() call is redundant since p.is_dir() returns False for nonexistent paths, but checking both would allow you to e.g. give better error messages. EDIT: Note that pathlib was added in Python 3.4. If you're still using an old version for whatever reason, you can use the ...
1. Python: Check if directory exists using os.path.exists() function os.path.exists()helps check if a specified path exists or not. It returns true if the path is a file, directory, or any other file that contains a reference to another file. ...
