Add Tab key to the Python command line auto-complement function

We are used to using the TAB key when using Linux commands, and we can implement similar functions in Python. The specific code is as follows:

$ cat startup.py
#!/usr/bin/python
# Python startup file
Import Sys
Import ReadLine
Import Rlcompleter
Import atexit
Import OS
# tab Completion
Readline.parse_and_bind (' Tab:complete ')
# History File
Histfile = Os.path.join (os.environ[' home '], '. Pythonhistory ')
Try
Readline.read_history_file (Histfile)
Except IOError:
Pass
Atexit.register (Readline.write_history_file, Histfile)
Del os, Histfile, ReadLine, Rlcompleter
View the Python default module storage path. copy function script to default module store path:

CP startup.py/usr/lib64/python2.x/

You can test this at this point in the following ways:

>>> Import OS
>>> os.<tab>
