In Python, a variable is a name given to a memory location to store data. Variables can hold different types of data, and their type is dynamically determined. Here are some common variable types in Python:
1. Integer (int):
Represents whole numbers without any decimal points.
```python
age = 25
```
2. Float (float):
Represents real numbers with decimal points.
```python
height = 5.8
```
3. String (str):
Represents a sequence of characters enclosed in single or double quotes.
```python
name = "John"
```
4. Boolean (bool):
Represents either True or False.
```python
is_adult = True
```
5. List:
Ordered collection of items.
```python
numbers = [1, 2, 3, 4, 5]
```
6. Tuple:
Similar to a list but immutable (cannot be changed after creation).
```python
coordinates = (3, 5)
```
7. Dictionary:
Unordered collection of key-value pairs.
```python
person = {'name': 'Alice', 'age': 30}
```
8. Set:
Unordered collection of unique items.
```python
unique_numbers = {1, 2, 3, 4, 5}
```
These are some fundamental variable types in Python. Each type has its own set of operations and use cases.
