    try:
  # Some code is here...
except:
  # some code is here...
    • if you suspect that a snippet may raise an exception, you should place it in the try block
    • The code that follows the try statement will be executed if the code in the except clause runs into an error.
    • The code that follows the except statement will be executed if the code in the try clause  runs into an error.
    • If there is a syntax error in code located in the try block, the except branch will not handle it, and a SyntaxError exception will be raised instead.

  17. Which one if the following lines properly starts a parameterless function definition?

    • def fun:
    • def fun():
    • function fun():

any()
print(var)
    • 12
    • 22
    • 11
    • 21

  21. The fact that tuples belong to sequence types means that:

    • they can be indexed and sliced like lists
    • they can be extended using the .append() method
    • they can be modified using the del instruction
    • they are actually lists

  22. A built-in function is a function which:
