Python context Manager

The context Manager enables allocation and deallocation of resources by using more readable and streamlined code

The most common use of the context manager is with the WITH statement, which constructs the allocation of resources and the release of syntactic sugars. Take the most common example, the opening and closing of a file.

Normal syntax:

f = file (filename,'w')   try:      f.write ('  Test file')   finally:      f.close ()

That is, normally, you want to display the open and close files. But if you use the WITH statement, it will be more readable and never worry about forgetting to close the file:

With file (filename,'w') as  F:      f.write ('test file ')
