# python startup file
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:
0
atexit.register(readline.write_history_file, histfile)
del os, histfile, readline, rlcompleter
在.profile文件中写入export PYTHONSTARTUP=$HOME/.pythonstartupfile
可以使用py3compile来编译文件,然后使用python3+文件名来运行
