# Basics

Data Types and Operators

`print ()` - built-in function that displays input values as text in the output

> The pythonic way to name variables is to use all lowercase letters and underscores to separate words. Example: `my_height = 58 my_lat = 40 my_long = 105`

## Arithmetic Operators

* `+` Addition
* `-` Subtraction
* `*` Multiplication
* `/` Division
* `//` Divides and rounds down to the nearest integer
* `%` Mod (the remainder after dividing)
* `**` Exponentiation (note that `^` does not do this operation, as you might have seen in other languages)

## Assignment Operators

* `=` Assignment
* `+=`  Addition Assignment
* `-=`  Subtraction Assignment
* `*=`  Multiplication Assignment
* `/=` Division Assignment
* `%=` Remainder Assignment
* `**=` Exponent Assignment

## Integers and Floats

* **int** - for integer values
* **float** - for decimal or floating point values

```python
x = int(4.7)   # x is now an integer 4
y = float(4)   # y is now a float of 4.0
```
