-A statement that assigns a value to a name (variable). Answer 1:
-Information in a program that is meant for other programmers (or anyone reading the source code) and has no effect on the execution of the program. Answer 2:
-The ability to combine simple expressions and statements into compound statements and expressions in order to represent complex computations concisely. Answer 3:
-To join two strings end-to-end. Answer 4:
-A set of values. Answer 5:
-To simplify an expression by performing the operations in order to yield a single value. Answer 6:
-A combination of variables, operators, and values that represents a single result value. Answer 7:
-A Python data type which stores floating-point numbers. Answer 8:
-A Python data type that holds positive and negative whole numbers. Answer 9:
-An operation that divides one integer by another and yields an integer. Answer 10:
-A reserved word that is used by the compiler to parse programs. Answer 11:
-One of the values on which an operator operates. Answer 12:
-A special symbol that represents a simple computation like addition, multiplication, or string concatenation. Answer 13:
-The set of rules governing the order in which expressions involving multiple operators and operands are evaluated. Answer 14:
-An instruction that the Python interpreter can execute. Answer 15:
-A Python data type that holds a string of characters. Answer 16:
