Eric V. Smith <[email protected]> added the comment:
We can't change the repr of int/float.
However, you can use sys.displayhook to achieve what you want:
import sys
def displayhook(o):
if o is None:
return
__builtins__._ = None
if isinstance(o, (int, float)):
print(format(o, '_'))
else:
print(repr(o))
__builtins__._ = o
sys.displayhook = displayhook
Then:
>>> 12312312
12_312_312
>>> 123123e123
1.23123e+128
>>> None
>>> 'test'
'test'
