- value:
- One of the basic units of data, like a number or string, that a program manipulates.
- type:
- A category of values. The types we have seen so far are integers (type int), floating-point numbers (type float), and strings (type str).
- integer:
- A type that represents whole numbers.
- floating-point:
- A type that represents numbers with fractional parts.
- string:
- A type that represents sequences of characters.
- variable:
- A name that refers to a value.
- statement:
- A section of code that represents a command or action. So far, the statements we have seen are assignments and print statements.
- assignment:
- A statement that assigns a value to a variable.
- state diagram:
- A graphical representation of a set of variables and the values they refer to.
- keyword:
- A reserved word that is used by the compiler to parse a program; you cannot use keywords like if, def, and while as variable names.
- operator:
- A special symbol that represents a simple computation like addition, multiplication, or string concatenation.
- operand:
- One of the values on which an operator operates.
- floor division:
- The operation that divides two numbers and chops off the fraction part.
- expression:
- A combination of variables, operators, and values that represents a single result value.
- evaluate:
- To simplify an expression by performing the operations in order to yield a single value.
- rules of precedence:
- The set of rules governing the order in which expressions involving multiple operators and operands are evaluated.
- concatenate:
- To join two operands end-to-end.
- comment:
- 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.
