EOF error with input

Question

Does anyone know why I get the EOF error when using input especially with while loop. If so, how can I correct this? Thanks.

Answer 1

Add: The actual code works first time but hits a snag on second loop.

Answer 2

Thanks Kit Delano Cat I forgot that sololearn only asks once. I got used to running code on IDE and having it ask for input at the start of each loop.
