Python add tab completion

It is convenient to check the Python method with tab completion in peacetime.

• 1. The Mac platform is configured as follows:
  • Mac is a Unix-like platform that needs to add a configuration to Bash_profile (default is no this file, you can create a new one under the host directory)
    • First create a new tab.py file with the following contents:

    • Importif'Darwin' and sys.version_info[0] = = 2:    Readline.parse_and_bind ("bind ^i rl_complete") Else :    readline.parse_and_bind ("tab:complete")

  
  
  • View the Python interpreter path for the current system

  • Copy the newly-created tab.py file to the interpreter path, usually placed under the '/library/python/2.7/site-packages/' directory
    • sudo cp tab.py/library/python/2.7/site/packages/
  • Writes information about the configuration file to ~/.bash_profile if it exists, adds it to the file content, and creates a new file if it does not exist
    • VI ~/.bash_profile Save exit then source ~/.bash_profile (let the profile take effect)

    • Export pythonstartup=/library/python/2.7/site-packages/tab.py

Then go to Python Import tab with tab to list the following sub-methods

2.Ubuntu system configuration file and Mac is a little different, also write a tab.py file to the Python interpreter path, the other operation is not used, add the following code:

sudo VI /usr/lib/python2. 7/dist-packages/tab.pyimport sys,readline,rlcompleter,atexit,osreadline.parse_and_bind ('  tab:complete'= Os.path. Join (os.environ['HOME'. Pythonhistory') Try:    readline.read_history_file (histfile) except IOError:    passatexit.register (Readline.write_history_file, Histfile) del os, Histfile, ReadLine, Rlcompleter
