How to save a data variable in Python using pickle library

# import pickle library

import pickle

# take user input to take the amount of data

number_of_data = int(input('Enter the number of data : '))
data = []

# take input of the data

for i in range(number_of_data):
    raw = input('Enter data '+str(i)+' : ')
    data.append(raw)

# open a file, where you want to store the data

file = open('important', 'wb')

# dump information to that file

pickle.dump(data, file)

# close the file

file.close()
