Datatypes

Python stores information as types.

Use the type function to see this information.

Remember syntax determines type.

type(42)

int

type(42.0)

float

type("Hello")

str

type([0, 1, 2])

list

type((0, 1, 2))

tuple

type({'a': 0, 'b': 1, 'c': 2})

dict

Special Types

type(True)

bool

type(False)

bool

type(None)

NoneType

Syntax Matters

Below examples show numeric and special values as string type because of the use of quotes.

type("42")

str

type("42.0")

str

type("True")

str

type("None")

str

Operators

Used to manipulate and evaluate values.

Basic operators inlcude: Mathematical, Logical, Comparison, and Assignment

Mathematical

Mathematical operators perform arithmetic calculations. In Python, these include + (addition), - (subtraction), * (multiplication), and / (division). Python uses // for integer division. Regular division will return a float value, while integer division will discard the remainder and return an integer.shown here, but available are also ** or ^ (exponentiation), and % or %% (modulus).

3 + 2

7 - 4

6 * 2

7 / 2

3.5

7 // 2

Comparison

Comparison operators evaluate relationships between values. Common operators in Python include == (equal), != (not equal), < (less than), <= (less than or equal to), > (greater than), and >= (greater than or equal to).

These return boolean values of True/False.

3 == 3

True

3 != 4

True

5 > 2

True

2 < 5

True

5 >= 5

True

4 <= 5

True

Logical

Logical operators allow for boolean logic. In Python: and, or, not. These are used in conditionals and loops to combine multiple logical expressions.

(3 > 1) and (2 < 5)

True

(3 > 1) or (2 > 5)

True

not (3 > 1)

False

Assignment and Equality

Assignment uses = to assign a value to a variable. x = 10 creates or updates the variable x to be 10.

Equality checking uses == and returns a Boolean (True, or False) depending on if the values are equal. x == 10 will return True if x is set as above.

x = 10
y = 10
x == y

True
