T or F: A function is defined using the reserved word define.

False

T or F: Functions do not return a value called "fruitful" functions.

False

T or F: The else keyword in a while loop specifies a block of code to be executed when the loop is finished.

False

T or F: The range() function defaults to increment the sequence by 2, however it is possible to specify the increment value by adding a second parameter: range(30,1)

False

T or F: The range(6) is not the values of 0 to 5, but the values 0 to 6.

False

T or F: The return value of a function can not be assigned to a variable

False

T or F: A break statement can stop a while loop even if the while condition is true.

True

T or F: A for loop is used for iterating over a sequence (like a list or a string).

True

T or F: A function is called using the function name followed by parentheses around an arguments.

True

T or F: A nested loop is a loop inside a loop.

True

T or F: A while loop will execute as long as a condition is true.

True

T or F: An argument is a value that is passed to a function as input when the function is invoked.

True

T or F: Built-in function names are treated as reserved words.

True

T or F: Calling a function is the same thing as invoking a function.

True

T or F: Functions must be defined and called separately.

True

T or F: In Python, a function is some reusable code that takes arguments(s) as input, does some computation, and then returns a result or results

True

T or F: In most cases the "inner loop" will be executed one time for each iteration of the "outer loop".

True

T or F: The for loop does not require an indexing variable to set beforehand.

True

T or F: The looping structures are using include for and while loops.

True

T or F: The range() function returns a sequence of numbers, starting from 0 by default, and increments by 1 (by default), and ends at a specified number.

True

T or F: The two kinds of functions in Python are built-in functions and functions we define ourselves.

True

T or F: With the loop we can execute a set of statements, once for each item in a list.

True

T or F:A function can be called many times with different arguments each time it is called.

True
