This article mainly introduces "what are the common functions of the os module of Python". In the daily operation, I believe that many people have doubts about the common functions of the os module of Python. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the questions of "what are the common functions of the os module of Python?" Next, please follow the editor to study!

Os.sep can replace operating system-specific path separators.

The os.name string indicates the platform you are using. For example, for Windows, it is' nt', 'and for Linux/Unix users, it is' posix'.

The os.getcwd () function gets the current working directory, which is the directory path where the current Python script works.

The os.getenv () and os.putenv () functions are used to read and set environment variables, respectively.

Os.listdir () returns all file and directory names under the specified directory.

The os.remove () function is used to delete a file.

The os.system () function runs the shell command.

The os.linesep string gives the line Terminator used by the current platform. For example, Windows uses'\ r\ n' while Mac uses'\ r'.

The os.path.split () function returns the directory name and file name of a path.

The os.path.isfile () and os.path.isdir () functions verify whether the given path is a file or a directory, respectively.

The os.path.existe () function is used to verify whether the given path really exists.

Os and os.path modules

Os.listdir (dirname): lists directories and files under dirname

Os.getcwd (): get the current working directory

Os.curdir: returns the previous directory ('.')

Os.chdir (dirname): change the working directory to dirname

Os.path.isdir (name): determines whether name is a directory, and name returns false if it is not a directory.

Os.path.isfile (name): determines whether name is a file, and returns false if name does not exist

Os.path.exists (name): determines whether a file or directory name exists

Os.path.getsize (name): gets the file size and returns 0L if name is a directory

Os.path.abspath (name): get the absolute path

Os.path.normpath (path): canonical path string form

Os.path.split (name): separate the file name from the directory (in fact, if you use the directory completely, it will also separate a directory as the file name, and it will not determine whether the file or directory exists)

Os.path.splitext (): separate the file name from the extension

Os.path.join (path,name): connect a directory to a file name or directory

Os.path.basename (path): returns the file name

Os.path.dirname (path): returns the file path

At this point, the study on "what are the common functions of the os module of Python" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
