有一种方法可以做到。将文件存储在~/.pystartup…

# Add auto-completion and a stored history file of commands to your Python
# interactive interpreter. Requires Python 2.0+, readline. Autocomplete is
# bound to the Esc key by default (you can change it - see readline docs).
#
# Store the file in ~/.pystartup, and set an environment variable to point
# to it:  "export PYTHONSTARTUP=/home/user/.pystartup" in bash.
#
# Note that PYTHONSTARTUP does *not* expand "~", so you have to put in the
# full path to your home directory.

import atexit
import os
import readline
import rlcompleter

historyPath = os.path.expanduser("~/.pyhistory")

def save_history(historyPath=historyPath):
    import readline
    readline.write_history_file(historyPath)

if os.path.exists(historyPath):
    readline.read_history_file(historyPath)

atexit.register(save_history)
del os, atexit, readline, rlcompleter, save_history, historyPath

然后在shell中设置环境变量PYTHONSTARTUP(例如在~/.bashrc中):

export PYTHONSTARTUP=$HOME/.pystartup

你也可以添加这个来获得免费的自动补全:

readline.parse_and_bind('tab: complete')

请注意，这只适用于*nix系统。因为readline只在Unix平台上可用。

你可以用内置函数打开:我用它在我的所有 我需要存储一些历史的程序(包括计算器等) 例如:

#gk-test.py or anything else would do
try: # use the try loop only if you haven't created the history file outside program
    username = open("history.txt").readline().strip("\n")
    user_age = open("history.txt").readlines()[1].strip("\n")
except FileNotFoundError:
    username = input("Enter Username: ")
    user_age = input("Enter User's Age: ")
    open("history.txt", "w").write(f"{username}\n{user_age}")
#Rest of the code is secret! try it your own!

我要感谢所有喜欢我评论的人!感谢您的阅读!

来自安德鲁·琼斯的网站(存档):

import readline
readline.write_history_file('/home/ahj/history')

如果您喜欢使用交互式会话，IPython是非常有用的。例如，在您的用例中，有一个%save magic命令，您只需输入%save my_useful_session 10-20 23，将第10行到第20行和第23行保存到my_useful_session.py(为了帮助实现这一点，每一行都有它的数字前缀)。

此外，文件指出:

此函数对输入范围使用与%history相同的语法，然后将行保存到指定的文件名。

例如，这允许引用旧的会话，例如

%save current_session ~0/
%save previous_session ~1/

我再提一个建议: 世爵

它有历史日志和变量资源管理器。如果你用过MatLab，你就会发现其中的相似之处。
