this looks relevant to my exception:

[that user's] code used to work until Python 3.4. I know because I've just run into the same issue, calling open() within del. Apparently built-in functions no longer work, because of a change in when del is run as the interpreter shuts down.
from wexpect.
I've run your snippet, with no error...
Can you describe your setup to help reporduce the issue?
from wexpect.
That snippet was just the setup, later in your test you would need to run some normal wexpect scenarios... spawning and expecting. Maybe this bug was only in the last release (v 3.3.0)?
from wexpect.
Also, are you using Python > version 3.4? I was using 3.6
from wexpect.
I use:
- Win 10.0.18362 Build 18362
- Python 3.7.5
Note, that wexpect requires Python 3.5 or higher because the Literal String Interpolation aka. Python f-Strings
I have added your snippet at the beginning of the hello_wexpect example which results the following code, but it still run with no errors.
I cannot reproduce your problem. Can you help me?
'''
This is the simplest example. It starts a windows command interpreter (aka. cmd) lists the current
directory and exits.
'''
import os
os.environ['WEXPECT_SPAWN_CLASS'] = 'SpawnPipe'
os.environ['WEXPECT_LOGGER_LEVEL']='INFO'
from wexpect import spawn
from wexpect import TIMEOUT, EOF
# Start cmd as child process
child = spawn('cmd.exe')
# Wait for prompt when cmd becomes ready.
child.expect('>')
# Prints the cmd's start message
print(child.before, end='')
print(child.after, end='')
# run list directory command
child.sendline('ls')
# Waiting for prompt
child.expect('>')
# Prints content of the directory
print(child.before, end='')
print(child.after, end='')
# Exit from cmd
child.sendline('exit')
# Waiting for cmd termination.
child.wait()
from wexpect.
ok, this issue is a result of me having a class in the file... it doesn't seem to matter where it's defined, before or after imports, before or after the wexpect
usage or wait
