# Python Faker Module

`Faker` is a Python package that generates fake data for you. Whether you need to bootstrap your database, create beautiful XML documents, fill-in your persistence to stress test it, or anonymize data taken from a production service, Faker is for you.

## Installation

```bash
pip install Faker
```

## Basic Usage

To use Faker, import the `Faker` class and create a new instance.

```python
from faker import Faker

fake = Faker()

print(fake.name())
# Output: 'Lucy Cechtelar'

print(fake.address())
# Output: '426 Jordy Lodge
#          Cartwrightshire, SC 88120-6700'

print(fake.text())
# Output: 'Sint velit eveniet. Rerum atque repet...'
```

## Localization

`Faker` supports multiple locales. You can pass a locale string to the constructor.

```python
from faker import Faker

fake = Faker('it_IT')

print(fake.name())
# Output: 'Eldda Palumbo'

print(fake.address())
# Output: 'Via Borgo 59
#          76015 San Paolo (CI)'
```

You can also pass a list of locales.

```python
fake = Faker(['en_US', 'ja_JP'])
for _ in range(5):
    print(fake.name())
```

## Seeding

To generate the same dataset every time (reproducibility), you can seed the generator.

```python
from faker import Faker

Faker.seed(0)
fake = Faker()

print(fake.name())
# Output will be consistent across runs
```

## Common Providers

Faker has many providers for different types of data.

*   **Profile**: `fake.profile()`, `fake.simple_profile()`
*   **Internet**: `fake.email()`, `fake.ipv4()`, `fake.url()`
*   **Credit Cards**: `fake.credit_card_number()`, `fake.credit_card_expire()`
*   **Date/Time**: `fake.date_of_birth()`, `fake.future_date()`

## Unique Values

If you need unique values, use the `.unique` property.

```python
names = [fake.unique.first_name() for _ in range(10)]
```
