When should I ever use file.read() or file.readlines()?

Question

I noticed that if I iterate over a file that I opened, it is much faster to iterate over it without \"read\"-ing it.

i.e.

l = open(\'file\',\'r\')

That was a brilliant answer. / Something good to know is that wheneever you use the readline() function it reads a line..... and then it won't be able to read it again. You can return to the position by using the seek() function. to go back to the zero position simply type in f.seek(0).

Similiarly, the function f.tell() will let you know at which position you are.
