Now I use:
pageHeadSectionFile = open('pagehead.section.htm','r') output = pageHeadSectionFile.read() pageHeadSectionFile.close()
But to make the code look better, I can do:
output = open('pagehead.section.htm','r').read()
When using the above syntax, how do I close the file to free up system resources?
Now we will see solution for issue: open read and close a file in 1 line of code
You don’t really have to close it – Python will do it automatically either during garbage collection or at program exit. But as @delnan noted, it’s better practice to explicitly close it for various reasons.
So, what you can do to keep it short, simple and explicit:
with open('pagehead.section.htm', 'r') as f: output = f.read()
Now it’s just two lines and pretty readable, I think.
