Python : write text to file line by line

This is how to print to a txt
file:

file = open("Exported.txt",
            "w")
file.write("Text to write to file")
file.close() #This close()
            is
            important

Another
way to do so would to be:

with
            open('Exported.txt', 'w') as file:
 file.write("Text to write to
            file")

This is a
program I made to write a txt
file:

import
            os.path


def start():

 print("What
            do you want to do?")
 print(" Type a to write a file")
 print(" Type
            b to read a file")
 choice = input(" -")
 if choice ==
            "a":
 create()
 elif choice == "b":

            read()

 else:
 print("Incorrect spelling of a or
            b\n\n")
 start()


def
            create():

 print()
 filename = input("What do you want
            the file to be called?\n")
 if os.path.isfile(filename):


            print("This file already exists")
 print("Are you sure you would like to
            overwrite?")
 overwrite = input("y or n")
 if overwrite ==
            "y":
 print("File has been overwritten")
 write(filename)

            else:
 print("I will restart the program for you")
 elif not
            os.path.isfile(filename):
 print("The file has not yet been
            created")

 write(filename)
 else:

            print("Error")





def
            write(filename):
 print()

 print("What would you like the
            word to end writing to be?")
 keyword = input()
 print("What would
            you like in your file?")
 text = ""
 filename = open(filename,
            'w')
 while text != keyword:
 filename.write(text)

            filename.write("\n")
 text =
            input()



def read():

            print()
 print("You are now in the reading area")
 filename =
            input("Please enter your file name: -")
 if
            os.path.isfile(filename):
 filename = open(filename, 'r')

            print(filename.read())
 elif not os.path.isfile(filename):

            print("The file does not exist\n\n")

 start()

            else:

            print("Error")


start()
