Tynker Python 201: Lessons 4 & 5 Vocab FLASHCARDS

Front

A symbol that modifies or combines values. For example, + and - are operators that add or subtract values.

Back

Operator

Front

A sequence of values or variables connected by operators. For example, b - a + 1 subtracts two variables and then adds the value 1.

Back

Expression

Front

An operator that only combines two values. Most of the operators that are commonly used in mathematical expressions like / and * are binary operators as the operation only involves the number before and after the operator.

Back

Binary Operator

Front

This operator is a binary operator that divides the first number by the second number and returns the remainder from that division operation. If the second number is a factor of the first number, the modulus operator will return 0.

Modulus

Front

In programming, this is the process of replacing a variable with the result of an operation and itself that increases the value stored in the variable. For example, x = x + 1 increments the value stored in x by 1.

Back

Incrementing

Front

In programming, this is the process of replacing a variable with the result of an operation and itself that decreases the value stored in the variable. For example, x = x/2 decrements the value stored in x by half of itself.

Back

Decrementing

Front

This is an expression that calculates a Boolean value using a mix of Booleans, variables, and operators.

Back

Logic/Boolean Expressions

Front

A value that is either True or False. In Python, True and False must be capitalized. Python equates True to the number 1, and False to the number 0. An empty string is considered False.

Back

Boolean

Front

This operator (==) will produce a Boolean value based on whether or not the left side is equal to the right side of an expression.

Back

"Equality" Operator

Front

This operator (!=) will produce a Boolean value based on whether or not the left side is not equal to the right side of an expression.

Back

"Not Equal" Operator
