Python script with a peculiar if and Else condition problem

Hello, gentlemen(the).

I’m a beginner in programming and I’m learning Python.

I wanted to ask a question about a program I created.

The program must create a fully filled tuple with an extension count, from zero to twenty. The program should then read a number on the keyboard (between 0 and 20) and display it in full. At the end of the program it should be shown if the user wants to continue typing (Conditions S (for yes) or N (for no).

I was able to complete the program partially, but note that when I put the program to "run" the non-identification error of the "if" condition is forgotten in the user’s first typing after the user has entered a non-existent option for the program. Only the second time he types N (saying he DOES NOT want to continue) is when the program actually finishesinserir a descrição da imagem aqui.

    Please [Edit] ask and add the source code. For reading more about in Manual on how NOT to ask questions.

  • "put the source code" is put the source code as text - not as an image. When pasting code as an image, anyone trying to collaborate cannot copy snippets of their code to respond, or even create a version that works - and is limited only to the code that appears on the screen.. In short: edit the question, remove this image, paste your source code, select it and click the button {} to format the code. Repeat the process with traceback (error message).

Friend, it happens because of the nature of your if's, one of them is whether the variable is 'N' and the other is whether the variable is not 'N', that is, if I press 'N' the first if will be true, and the second will also be true.

Consider using a if-elif
