Introduction

Recently, I had a requirement to fill the database with some data. Filling the tables manually proved to be very tedious enough. So, I was looking for some software that could do the heavy lifting for me and also that could be used with Python natively. Voila!! After a bit of search came across this awesome software.

FAKER

Faker can be used to generate fake data which resembles the real world values rather than some gibberish values.

Using FAKER With Python

The following code has been tested using Python 3.5 on a Windows 10 machine.

Type the below command in the Command Prompt to install Faker module.

Let’s start with a very simple example.

Import the faker module and make use of the Factory Class. Use create() method to create an object called fake. Say, if you want to print a name then use the object fake along with name() method as shown below.

from faker import Factory
fake = Factory.create()
print(fake.name())

Output

Susan Craig

You can even localize the names according to your preferences.

For example, if you want to display name in Hindi (India), then pass the string argument “hi_IN” to create() method.

from faker import Factory
fake = Factory.create("hi_IN")
print(fake.name())

Output

रामशर्मा, निशा

If you want to display 10 random currencies

from faker import Factory
fake = Factory.create()
for i in range(10):
    print(fake.currency_code())

Output

IDR
TZS
SZL
TZS
JOD
MZN
RSD
HUF
SZL
USD

You can randomly generate addresses using address() method. Below code is localized for “en_US”.

from faker import Factory
fake = Factory.create("en_US")
for i in range(10):
    print(fake.address())

Output

You can generate various information about a person using different methods as shown below.

from faker import Factory
fake = Factory.create("en_US")

print(fake.last_name_male())

print(fake.name_female())

print(fake.prefix_male())

print(fake.prefix())

print(fake.name())

print(fake.suffix_female())

print(fake.name_male())

print(fake.first_name())

print(fake.suffix_male())

print(fake.suffix())

print(fake.first_name_male())

print(fake.first_name_female())

print(fake.last_name_female())
