Answer 1

Question -1

Answer :

All of the above

Explanation

While using the functions in any programming language then the program will be more organized and the length of the program will decrease, which improves the readability of the program.

Question – 2

Answer:

The code immediately after where the function was called from.

Explanation

          It is the properties of any language is that the execution of the statements will be one after another. So after completion of a function then it will execute the immediate statement after its call.

Question – 3

Answer:

The next non-blank line of code is indented at the same indentation level as the def statement for the function.

Explanation

          In python the indentations plays an vital role for formation of blocks. So after the completion of a function the next statement will be on same indentation level as def statement.

Example:

In the above code the function terminates just before the statement

a=int(input(“Enter a number”))

Question – 4

Answer:

If it is a function call, it will have parentheses after the name to call the function.

Explanation:

In any programming language the function name always terminated by a pair of parenthesis.

Question – 5

Answer:

Parameters that are passed to the function and any variables created in the function.

Explanation:

The function can use the variables that are passed to it as argument and if any other variable declared inside it then those can also be used inside the function. Other variables can not be used by function because of those will be out of scope rules.

Question – 6

Answer :

The order of the parameters indicates how they are assigned.

Explanation

During the function call one have to maintain the order of parameters according to these the parameters will assign in the definition part of function as formal parameters.

Question - 7

Answer:

To send a value or values back to the code that called it.

Explanation:

The return statement will return the final result of function to its calling part that means the statement which called to the function.

Question -8

Answer

assign it to a variable (e.g., x = math.sqrt(5))

Explanation

Since the function will return a value so assign it to a variable.

Question -9

Answer:

store the result in a variable

Explanation

Since the function will return a value so assign it to a variable
