Creating file from editor

[snippsat]

f.read('hello world')

It's just f.read().
The point of using with open() is that the file will be closed automatically.
So trow away all close()

with open('bacon.txt', 'w') as f:
    f.write('hello world')

with open('bacon.txt') as f:
    print(f.read())

Output:
hello world
