Description

If I run a python script, exception is occurring only in NB. If I execute the same script with same python interpreter on command line, no exception is raised.

Created sample project "sample_1" with a python test source file. After running the project NB output window showing below error:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

def main():
child = wexpect.spawn('telnet 10.61.252.10')
child.logfile_read = sys.stdout
child.expect('Enter your user-id/password and clearance level:')

If I execute same file in Windows command line, no exception occurs:

Reproducible in both NB8.2 and NB11.0
