First up, it's an error, you didn't close the " and ) on the last line...

this code will keep repeating the three lines of text. I expect that after this there is a prompt to the user to fill in the text, but this code only displays the text. while will keep repeating the code until the condition is false. because it isn't a check like i<5 it will only stop if the loop is aborted with a return or break

its calculator.... the coder is giving u the way by tht u can add or substract or multiply numbers... while True: # this part always executes ...if you give a break statement...in while loop then on that satisfying condition the loop breaks out.. usually while loop is used because... u and user both dont know where to stop... or when to stop.. u may have to use that program for calculation fr an hour or fr some minute... suppose theres a input in that while loop.. and whenever the input is "n" it breals through the loop... and continue if the input is "y" or anything else... i hope u understood
