Text is not being written to a text file?

Question

Python

Started learning Python. Looked at the lesson on working with files.
create a text document named 'text'. Next, I write the following code:
file = open ('text.txt', 'w')
file.write('Hello')
After that, the word 'Hello' should appear in the file, but it is not there. The python file and the document are in the same folder.
