Python Cert - Day 4 (PM)

A function definition starts with the keyword:

• def

• function

• fun

A function definition:

• cannot be placed among other code

• may be placed anywhere inside the code after the first invocation

• must be placed before the first invocation

A function parameter is a kind of variable accessible:

• only after the function definition's completion

• anywhere in the code

• only inside the function

A way of passing arguments in which the order of the arguments determines the initial parameters' values is referred to as:

• positional

• ordered

• sequential

• keyword

Which of the following statements are TRUE? (Select TWO answers)

• The return keyword may cause the function to return a value

• The return keyword forces the function's execution to terminate

• The return keyword forces the function to restart its execution

None keyword designates:

• a None value

• a function which doesn't return a value

• an empty instruction

A variable defined outside a function:

• may not be accessed in any way inside the function

• may be read, but not written (something more is needed to do so)

• may be freely accessed inside the function

If a list is passed into a function as an argument, deleting any of its elements inside the function using the del instruction:

• will affect the argument

• will cause a runtime error

• will not affect the argument
