Cannot delete None at the bottom

Using Streamlit
1

I try to prepare a questionnaire of 5 yes no questions.

The problem is after the result line at the end there are 5 lines only written as None.

The code is :slight_smile:

answers = [‘Yes’, ‘No’]

question_1 = tab_2.radio(‘1.tired.’, answers)

tip_1.append(1) if question_1 == ‘Yes’ else tip_1.append(0)

question_2 = tab_2.radio(‘2.dizzy.’, answers)

tip_5.append(1) if question_2 == ‘Yes’ else tip_5.append(0)

question_3 = tab_2.radio(‘3.Nausea.’, answers)

tip_9.append(1) if question_3 == ‘Yes’ else tip_9.append(0)

question_4 = tab_2.radio(‘4.Vomit.’, answers)

tip_2.append(1) if question_4 == ‘Yes’ else tip_2.append(0)

question_5 = tab_2.radio(‘5.Headache.’, answers)

tip_8.append(1) if question_5 == ‘Yes’ else tip_8.append(0)

sum_lists = [sum(tip_1), sum(tip_2), sum(tip_3), sum(tip_4), sum(tip_5), sum(tip_6), sum(tip_7), sum(tip_8), sum(tip_9)]

max_list_index = sum_lists.index(max(sum_lists))

tab_2.write(f"Your type is tip{max_list_index + 1}")

In the website, after the result line there are 5 lines of None

None

None

None

None

I couldn’t get rid of them.

I have three tabs and I have these five None line in each of the tabs.

Could you please help me?

Try turning off Streamlit Magic. Or terminate the if/else constructs with a semi-colon.

Hi @Yusuf_Gungoray

Agreeing with @asehmi that the if/else formatting may be the cause of the problem:

Try refactoring the code in the following structure:

if question_1 == ‘Yes’:
   tip_1.append(1)
else:
   tip_1.append(0)
