本文介绍了如何配置ipython以十六进制格式显示整数?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
这是默认行为:
In [21]: 255
Out[21]: 255
这就是我想要的:
In [21]: 255
Out[21]: FF
我可以设置ipython吗?
Can I setup ipython to do that?
推荐答案
您可以通过为int注册特殊的显示格式化器来完成此操作:
You can do this by registering a special display formatter for ints:
In [1]: formatter = get_ipython().display_formatter.formatters['text/plain']
In [2]: formatter.for_type(int, lambda n, p, cycle: p.text("%X" % n))
Out[2]: <function IPython.lib.pretty._repr_pprint>
In [3]: 1
Out[3]: 1
In [4]: 100
Out[4]: 64
In [5]: 255
Out[5]: FF
如果你想要这个永远在线,你可以在 $(ipython locate profile)/startup/hexints.py
中用前两行创建一个文件(或者作为一个避免任何分配):
If you want this always-on, you can create a file in $(ipython locate profile)/startup/hexints.py
with the first two lines (or as one to avoid any assignments):
get_ipython().display_formatter.formatters['text/plain'].for_type(int, lambda n, p, cycle: p.text("%X" % n))
将被执行每次启动IPython。
which will be executed every time you start IPython.
