Python 201 Lessons 2&3 Vocab

Used to store values at a named location in a computer's memory. They can have many types such as integers, strings, or booleans. To access the value in the variable, simply use the name of the variable and the name will be replaced with the value when the program is executed.

• Variable
• Variable Assignment
• Reassigning Variables
• Return Value
• Data Type

An instruction that assigns a value to a variable. For example, the instruction country = "USA" assigns the value "USA" to the variable country.

• Variable Assignment
• Variable
• Reassigning Variables
• Return Value
• Data Type

Removes the old value stored in the variable and replaces it with the new value that is assigned to it

• Reassigning Variables
• Variable
• Variable Assignment
• Return Value
• Data Type

A value that a function outputs once the function has been run. This value can be stored in a variable or used in another calculation.

• Return Value
• Variable
• Variable Assignment
• Reassigning Variables
• Data Type

A particular kind of data. The type of the data determines what operations or functions can be performed on that data. Different data types cannot be combined with each other without converting the data type. Strings, integers, floats, and booleans are examples of data types in Python.

• Data Type
• String

• Float

• Integer

• Return Value

A sequence of characters (letters) enclosed in either double or single quotes.

• String
• Variable
• Integer

• Float

• Boolean

Joining two or more strings together to make one longer string by using a + symbol between the two strings.

• Concatenate
• Boolean

• Variable Assignment
• Reassigning Variables
• Return Value

A positive or negative whole number. They should not be enclosed in quotation marks. They should be treated just like numbers and can be used in mathematical calculations.

• Integer
• Variable
• String

• Float

• Data Type

A number with decimal precision that is always displayed with a decimal point. When you combine floats and integers in a mathematical calculation, the resulting answer will always be a float.

• Float
• Variable
• Integer

• String

• Concatenate

A value that is either True or False. In Python, the T and F in true and false must be capitalized. These values are often used to create branching logic in programs.

• Boolean
• Variable
• Float

• Concatenate

• Return Value
