In this Tutorial we will learn about the some important library in python and their different uses in real time projects.

1.Python Facker Library

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

Faker has the ability to print/get a lot of different fake data, for instance, it can print fake name, address, email, text, etc.

pip install Faker

from faker import Faker
#'hi_IN' changed the language
# fake = Faker('hi_IN')   
fake = Faker()
# fake.seed(1)   #if you need same data again and again you can used seed() method 
print (fake.email())
print(fake.country())
print(fake.name())
print(fake.text())
print(fake.latitude(), fake.longitude())
print(fake.url())
print(fake.profile())
print(fake.sentence()) # to print random sentence
"""
if you want the sentence only from particular words then
"""
# List has words that we want in our sentence 
word_list = ["Nepal", "Engineer",
             "Salary", "Messi", "Cricket",
             "family"]
# lets create 5 sentence from the above words 
for i in range(0, 5): 
    # You need to use ext_word_list = listnameyoucreated 
    print(fake.sentence(ext_word_list = word_list)) 

Lets insert data using facker Library

from faker import Faker 
  
# To create a json file
import json        
  
# For student id 
from random import randint     
  
fake = Faker() 
  
def input_data(x): 
  
    # dictionary 
    student_data ={} 
    for i in range(0, x): 
        student_data[i]={} 
        student_data[i]['id']= randint(1, 100) 
        student_data[i]['name']= fake.name() 
        student_data[i]['address']= fake.address() 
        student_data[i]['latitude']= str(fake.latitude()) 
        student_data[i]['longitude']= str(fake.longitude()) 
    print(student_data) 
  
    # dictionary dumped as json in a json file 
    with open('students.json', 'w') as fp: 
        json.dump(student_data, fp) 
      
  
def main(): 
  
    # Enter number of students 
    # For the above task make this 100 
    number_of_students = 10 
    input_data(number_of_students) 
main() 
# The folder or location where this python code 
# is save there a students.json will be created 
# having 10 students data.
