The python os module mainly manipulates files and directories. The commonly used methods are as follows:
# 1. os.getcwd() to get the directory where the current file is located # 2. os.makedirs('dirname1/dirname2') to create a directory, which can generate multiple recursive directories # 3. os.removedirs('dirname1/dirname2') to delete a directory , must be an empty directory # 4. os.mkdir() creates a single directory # 5. os.rmdir() deletes the empty directory, if there is no error # 6. os.listdir('dirname') lists all the files in the specified directory files and subdirectories, including hidden files, and print them as a list # 7, os.remove() removes files # 8, os.sep returns the file separator for the current system, \ for Windows, / # 9 for linux, os.linesep Output the line terminator used by the current platform, "\t\n" under win, "\n" under Linux # 10. os.pathsep Output the string used to split the file path as; under win, under Linux: # 11. os.environ gets system environment variables
