# Basics of variables

## Variables are containers that are used to store data

Example:

```python
number = 77
print(number)
```

Expression:

```python
weight = 22
number = 77

answer = number + weight
# reutrns 99
```

Concatenation = adding STRINGS together - `Concatenation only works with strings`

```python
first_name = tinerica
last_name = popica

name = first_name + lastname
print(name) #returns tinericapopica
```
