I would like to have the user enter a response of that response would create a "variable" or not. I do not know if creating a new variable would be the best way, for example:
a = str(input('Existe mais produtos para serem adicionados?: '))
In this part the user would answer yes or no , if the answer were yes , the program would create another variable that would receive a certain value float
(a2 a3 a4) and so on.
