# Importing csv module
import csv

# empty list to store data
data = []
columns = ["firstname", "lastname", "grade1", "grade2", "grade3"]
filename = "grades.csv"

for i in range(3):
firstname = input("Enter First Name : ")
lastname = input("Enter Last Name : ")
grade1 = float(input("Enter Grade 1 : "))
grade2 = float(input("Enter Grade 2 : "))
grade3 = float(input("Enter Grade 3 : "))
data.append([firstname, lastname, grade1, grade2, grade3])
print()

# write data and columns as csv file
with open(filename, 'w') as csvfile:
# creating a csv writer object
csvwriter = csv.writer(csvfile)

# writing the columns
csvwriter.writerow(columns)

# writing the each row to the data
csvwriter.writerows(data)

print("CSV file {} has been created successfully!!".format(filename))
