Can't write to a .txt file in Python

This is my code:

import os
os.chdir("C:\Users\satvi_000\Downloads")

if os.path.exists('new_file.txt')==False:  
    create_file= open("new_file.txt",'w')  #This is just to  create the file 
                                                  #in case it doesn't exist
    create_file.close()
file= open('new_file.txt','r+')

data= file.read()

file.write("blah blah blah ")

I want to create a file( if it doesn't already exist) and write some data to it. I'm doing this as a part of a larger program and tested it separately to see what the problem was and I can't quite figure it out yet. I will be writing to this file again and again in the larger program, and the file will also be modified everytime the program is run. What's going wrong here?
