[issue42852] pprint fails in transformming non-breaking space

[Steven D'Aprano]

Steven D'Aprano  added the comment:

By the way, there is no need to use the u'' prefix on strings in Python 3.

Unfortunately, I think this is a case where pprint doesn't meet your 
expectations. pprint is designed to print the repr of a string, while regular 
print prints the human-visible str:

>>> print(repr('\240 hello'))
'\xa0 hello'
>>> print('\240 hello')
  hello

Its not just non-breaking space, it also includes ASCII characters:


>>> print(repr('\01 hello'))
'\x01 hello'
>>> print('\01 hello')
 hello
>>> pprint.pprint('\01 hello')
'\x01 hello'


So this is intentional behaviour, not a bug. If you want to change the 
behaviour, it will probably require a re-design of the way strings are printed 
by the pprint module.

[issue42852] pprint fails in transformming non-breaking space

[Xinmeng Xia]

New submission from Xinmeng Xia :

"pprint" can transform unicode like "print". However, pprint fails to transform 
non-breaking space('\240') . See the following example:

Python 3.10.0a2 (default, Nov 24 2020, 14:18:46) 
[GCC 7.5.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

Example 1(Results as expected):
-
>>> import pprint
>>> print(u'\041 hello')
! hello
>>> pprint.pprint(u'\041 hello')
'! hello'

Example 2(Results not as expected):
-
>>> print(u'\240 hello')
  hello
>>> pprint.pprint(u'\240 hello')
'\xa0 hello'

Expected output: the output of pprint.pprint(u'\240 hello') should be 
consistent with output of print(u'\240 hello')
