Faker Basicsįaker is easily able to handle basic biographic information such as name, address, phone number, sign-post other providers. This post gives an overview of the Python fake data package faker, which is invaluable for generating this data. This lets you protect your production data or help you get started when you don’t yet have a production system set up. This is quite helpful when you are generating data like ID, that does not need to be repeated.įaker also has a method to generate a dummy profile.Fake data can be invaluable for testing or demonstrating behaviour without using live, production data. > time the above code runs, it will generate 5 unique email addresses. unique property of the generator.įor i in range(10): # generates 5 unique random emails So, to create unique dummy data using the Faker package, you can use the. > when the data gets bigger, there is a chance that you would get the same email address more than once. Each time, the below code generates 5 random names.įor i in range(5): # generates 5 random emails Let’s say you want to generate a list of 5 email addresses. Sure do memory kitchen candidate fish defense. Moreover, the ntence() method will return a string containing a random sentence, whereas faker.text() will return a randomly generated text.įake.sentence() # Returns a random sentenceĪs can be seen below faker.text() generates a random paragraph. To create addresses, you can use the address(). Note that, each call to these methods will generate a random name. However, if you want the only first or last name instead, you can use the first_name() and last_name() methods. Let’s jump into the code and check how these methods work. The name() method can be used to create a full name. A fake is generated when the method corresponding to the data type is called. Its purpose is to act as a substitute or placeholder for the actual data. As the name suggests, it is fake data that is randomly generated. Now, you are ready to generate whatever data you want. If you want to initialise Faker in other languages you need to specify the language parameter (eg. While the first line imports the generator (Class Faker), the second one is used to initialise the generator with English as a default language parameter. With the following two lines of code you can initialise Faker. The installation can be done via pip with the command: Let’s take a look at how to use it in terms of codes. Providers –generators specific to a certain type of data– are added regularly by the community. Since Faker is an open library for the community, it is constantly evolving. Installation and Useįaker allows you to generate random data in dozens of languages. In this article, we’ll take a quick tour of Faker’s features and how to use them to create a dummy dataset. Faker is an open source library designed to generate different types of synthetic data. With Python, you can use the Faker package to generate data according to your data needs. So, where do you get dummy data for your own application? There is an elegant solution to this problem in the form of the Faker package. However, finding the necessary data in a specific format we want can be difficult. That is, to test what you have developed and how your code reacts to different types of input. You may also need to generate dummy data for testing and operational purposes. Whether for testing, anonymising sensitive data, or adding “noise” to a training dataset, it can be beneficial to have access to a fake dataset in the same shape as the real data. Fictitious data is required for a variety of purposes.
