Faker is a Python package that generates fake data for you.

A library that can quickly generate dummy data when you need it, such as right after creating a new DB or when writing unit tests. LLMs work too, but this is useful in airgap, CI, lightweight VM environments, and the like.

Example

• fake.name() - name
• fake.address() - address
• fake.postcode() - postal code
• fake.country() - country name
• fake.company() - company name
• fake.job() - job title
• fake.phone_number() - mobile phone number
• fake.email() - email address
• fake.user_name() - username
• fake.pyint(min_value=0, max_value=100) - random number between 0 and 100
• fake.ipv4_private() - IP address
• fake.text() - random sentence (※ for random Korean sentences, use fake.catch_phrase())
• fake.color_name() - color name
