[CentralOH] Files and context manager

[Mark Erbaugh]

Hi,

A common idiom with older versions of Python is:

x = open(filename,'rb').read()

With context managers in 2.6+ you could say:

with open(filename,'rb') as f:
	x = f.read()

Is the later safer in that it explicitly will call close() whereas the former depends on the file destructor to close the file?

Thanks,
Mark
