Issue 32490: subprocess: duplicate filename in exception message (original) (raw)

Python 3.6.4 (default, Jan 3 2018, 21:10:22) [GCC 4.8.4] on linux Type "help", "copyright", "credits" or "license" for more information.

import subprocess subprocess.call('nonexistent') Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python3.6/subprocess.py", line 267, in call with Popen(*popenargs, **kwargs) as p: File "/usr/local/lib/python3.6/subprocess.py", line 709, in init restore_signals, start_new_session) File "/usr/local/lib/python3.6/subprocess.py", line 1344, in _execute_child raise child_exception_type(errno_num, err_msg, err_filename) FileNotFoundError: [Errno 2] No such file or directory: 'nonexistent': 'nonexistent'

Note that the name of the missing file is mentioned twice in the error message. (Strictly speaking it's once in the message, and once in the filename attribute, but for a casual observer, the effect is the same.)
