Catching a crash within a library code

[BashBedlam]

If you do this:

import numpy
array = numpy.array ([one, two, three])

It will throw this error:

Error:
Traceback (most recent call last):
  File "tester.py", line 15, in <module>
    array = numpy.array ([one, two, three])
NameError: name 'one' is not defined

That last line and in particular

Error:
NameError

is the information you need to use the try/except block. Try this:

import numpy
try :
	array = numpy.array ([one, two, three])
except NameError as e :
	print('*** ERROR ***', str(e))
