How this file can be closed. Any idea?
with open('output.txt','w', encoding='UTF-8') as output:
output.writelines(str(i)+'\n' for i in range(5))
The file is automatically closed when you leave the “
with-block” or an exception is encountered. This is why it’s the preferred way to open files.See this PEP 343 — The “with” Statement for more information on the
withstatement. The Python “with” Statement by Example gives more information.UPDATE:
Your inability to delete a file opened with
withwas due to the file having been left open previously (when not usingwithand not explicitlycloseing it). As a test using a different file andwithdidn’t create a problem.
