使用readline.get_current_history_length()获取长度，并使用readline.get_history_item()查看每个长度。

这应该会让你在单独的行中打印出命令:

import readline
map(lambda p:print(readline.get_history_item(p)),
    map(lambda p:p, range(readline.get_current_history_length()))
)

使用python3解释器，历史记录被写入 ~ / .python_history

@Jason-V，真的很有帮助，谢谢。然后，我找到了这个例子，并组成了自己的片段。

#!/usr/bin/env python3
import os, readline, atexit
python_history = os.path.join(os.environ['HOME'], '.python_history')
try:
  readline.read_history_file(python_history)
  readline.parse_and_bind("tab: complete")
  readline.set_history_length(5000)
  atexit.register(readline.write_history_file, python_history)
except IOError:
  pass
del os, python_history, readline, atexit 

在IPython中，%history -g应该提供整个命令历史。

默认配置还将历史记录保存到用户目录中名为.python_history的文件中。

重新讨论一下Doogle的答案，它不打印行数，但允许指定要打印的行数。

def history(lastn=None):
    """
    param: lastn Defaults to None i.e full history. If specified then returns lastn records from history.
           Also takes -ve sequence for first n history records.
    """
    import readline
    assert lastn is None or isinstance(lastn, int), "Only integers are allowed."
    hlen = readline.get_current_history_length()
    is_neg = lastn is not None and lastn < 0
    if not is_neg:
        for r in range(1,hlen+1) if not lastn else range(1, hlen+1)[-lastn:]:
            print(readline.get_history_item(r))
    else:
        for r in range(1, -lastn + 1):
            print(readline.get_history_item(r))
