Whats A Priming Input Statement Python

It is the input operation that takes place just before an input validation loop. The purpose of the priming read is to get the first input value. If the input that is read by the priming read is valid, how many times will the input validation loop iterate?

I have a function that evaluates input, and I need to keep asking for their input and evaluating it until they enter a blank line. input Get the input while inp ! quotquot Loop until it is a blank line inp raw_input Get the input again Note that if you are on Python 3.x, you will need to replace raw_input with input.
