This set of Problem Solving and Python Programming Multiple Choice Questions & Answers (MCQs) focuses on Problem Solving And Python Programming Set 19

Q1 | ))
  • 120
  • nothing is printed
  • error, method factorial doesn’t exist in math module
  • error, the statement should be: print(factorial(5))
Answer: error, the statement should be: print(factorial(5))
Explaination:
in the “from-import” form of import, the imported identifiers (in this case factorial()) aren’t specified along with the module name.
Q2 | What is the order of namespaces in which Python looks for an identifier?
  • python first searches the global namespace, then the local namespace and finally the built- in namespace
  • python first searches the local namespace, then the global namespace and finally the built-in namespace
  • python first searches the built-in namespace, then the global namespace and finally the local namespace
  • python first searches the built-in namespace, then the local namespace and finally the global namespace
Answer: python first searches the local namespace, then the global namespace and finally the built-in namespace
Explaination:
python first searches for the local, then the global and finally the built-in namespace.
