Is file object in python an iterable

Question

this is 1st line
this is 2nd line
this is 3rd line

the following code

lines = open(\"test.txt\"         


        

Answer 1

It is not only an iterable, it is an iterator, which is why it can only traverse the file once. You may reset the file cursor with .seek(0) as many have suggested but you should, in most cases, only iterate a file once.
