[New-bugs-announce] [issue13532] In IDLE, sys.stdout.write and sys.stderr can write any pickleable object

[maniram maniram]

New submission from maniram maniram <maniandram01 at gmail.com>:

In IDLE, sys.stdout.write and sys.stderr can write any pickleable object such as 100 when they should only allow strings.
IDLE seems to be pickling the object.
>>> import sys
>>> sys.stdout.write(100)
100
>>> sys.stdout.write(sys)
Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    sys.stdout.write(sys)
_pickle.PicklingError: Can't pickle <class 'module'>: attribute lookup builtins.module failed
The error above is more detailed in IDLE 2.7.
While in Python on the command-line:
>>> import sys
>>> sys.stdout.write(100)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: must be str, not int
>>> 
The error above in Python 2.7:
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: expected a character buffer object
