Python中tab鍵自動補全功能的設定
2020-06-16 17:39:14
新手學習Python的時候,如何沒有tab鍵補全功能,我感覺那將是一個噩夢,對於我們這種菜鳥來說,剛接觸python,對一切都不了解,還好有前輩們的指導,學習一下,並記錄下來,還沒有學習這個功能小夥伴們!趕緊get吧!
- 1.首先我們需要檢視python的安裝路徑
[root@localhost ~]# python
Python 2.6.6 (r266:84292, Oct 12 2012, 14:23:48)
[GCC 4.4.6 20120305 (Red Hat 4.4.6-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.path
['', '/usr/lib64/python26.zip', '/usr/lib64/python2.6', '/usr/lib64/python2.6/plat-linux2', '/usr/lib64/python2.6/lib-tk', '/usr/lib64/python2.6/lib-old', '/usr/lib64/python2.6/lib-dynload', '/usr/lib64/python2.6/site-packages', '/usr/lib64/python2.6/site-packages/gst-0.10', '/usr/lib64/python2.6/site-packages/gtk-2.0', '/usr/lib64/python2.6/site-packages/webkit-1.0', '/usr/lib/python2.6/site-packages']
- 切換目錄到python的安裝目錄下,進行tab鍵補全模組的編寫。
[root@localhost ~]# cd /usr/lib64/python2.6
[root@localhost python2.6]# vim tab.py
#!/usr/bin/env 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
- 此處我們編寫完成後就可以進入python中匯入tab鍵補全
root@localhost python2.6]# python

sys.__init__( sys._clear_type_cache( sys.exc_type sys.getrefcount( sys.ps1 sys.warnoptions

sys.__reduce__( sys.argv sys.exit( sys.maxint sys.setdlopenflags(
- 為了進入python之後不用每次都匯入,來進行下邊的操作,進入家目錄,編寫 .bashrc檔案在最後新增下面一行,儲存退出。
[root@localhost ~]# cd ~
[root@localhost ~]# vim .bashrc
export PYTHONSTARTUP=/usr/lib64/python2.6/tab.py
- 家目錄.bashrc檔案只有使用者登入時才會載入生效,需要進行下面的操作來生效
[root@localhost ~]# source .bashrc
OK,那麼現在我們就可以不用每次進行python之後進行import tab 動作來使tab鍵補全功能生效了。
