2.14. Glossary¶
- Assignment¶
A statement that assigns a value to a variable.
- 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.
- Evaluate¶
To simplify an expression by performing the operations in order to yield a single value.
- Expression¶
A combination of variables, operators, and values that represents a single result value.
- Floating Point¶
A type that represents numbers with fractional parts.
- Integer¶
A type that represents whole numbers.
- Keyword¶
A reserved word that is used by the compiler to parse a program; you cannot use keywords like
if,def, andwhileas variable names.- Mnemonic¶
A memory aid. We often give variables mnemonic names to help us remember what is stored in the variable.
- Modulus Operator¶
An operator, denoted with a percent sign (
%), that works on integers and yields the remainder when one number is divided by another.- Operand¶
One of the values on which an operator operates.
- Operator¶
A special symbol that represents a simple computation like addition, multiplication, or string concatenation.
- Rules of Precedence¶
The set of rules governing the order in which expressions involving multiple operators and operands are evaluated.
- Statement¶
A section of code that represents a command or action. So far, the statements we have seen are assignments and print expression statement.
- String¶
A type that represents sequences of characters.
- Type¶
A category of values. The types we have seen so far are integers (type
int), floating-point numbers (typefloat), and strings (typestr).- Value¶
One of the basic units of data, like a number or string, that a program manipulates.
- Variable¶
A name that refers to a value.
