Python try block does not catch os.system exceptions

Question

I have this python code:

import os
try:
  os.system(\'wrongcommand\')
except:
  print(\"command does not work\")

The code prints:

Answer 1

wrongcommand: command not found is the output of the shell os.system is using to invoke the command. os.system did not throw an exception
