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?
答案 0 :(得分:22)
您可以通过为int注册特殊的显示格式化器来完成此操作:
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(或者作为一个文件来避免任何分配):
get_ipython().display_formatter.formatters['text/plain'].for_type(int, lambda n, p, cycle: p.text("%X" % n))
每次启动IPython时都会执行。

在另一个问题上基于minrk's answer和rjb's answer,我把它放在我的Python启动文件中:
def hexon_ipython():
'''To print ints as hex, run hexon_ipython().
To revert, run hexoff_ipython().
'''
formatter = get_ipython().display_formatter.formatters['text/plain']
formatter.for_type(int, lambda n, p, cycle: p.text("0x%x" % n))
def hexoff_ipython():
'''See documentation for hexon_ipython().'''
formatter = get_ipython().display_formatter.formatters['text/plain']
formatter.for_type(int, lambda n, p, cycle: p.text("%d" % n))
hexon = hexon_ipython
hexoff = hexoff_ipython
所以我可以这样使用它:
In [1]: 15
Out[1]: 15
In [2]: hexon()
In [3]: 15
Out[3]: 0xf
In [4]: hexoff()
In [5]: 15
Out[5]: 15
