I am a very new beginner in python programming so I hope my question makes sense.
I want to make a program of a medical interview with guided questions depending on the user answers to previous questions.
I started with basic if/else structure but I am blocked because I don't know how to ask something in an if/else structure. For example:
A = input("Question 1 ? ")
if A == "yes":
print("Consequence of yes to question 1")
else:
A == "no"
print("Consequence of no to question 1")
if A == "no":
B = input("Question 2 ?")
It seems I can't put input
statement in an if
statement because when I run, it does not take the B = input("Question 2?")
into account. But I need to assign a yes/no answer to Question 2 so I can pursue the interview. All I saw on the internet is print
statements in if/else structure. I also tried to do nested if
statements but it doesn't work.
Could someone help me please? Thanks a lot
You can do an elif
statement, it's else
and if
combined, so what it means is that if the first condition isn't true, check if this one is true:
A = input("Question 1 ? ")
if A == "yes":
print("Consequence of yes to question 1")
elif A == "no":
print("Consequence of no to question 1")
if A == "no":
B = input("Question 2 ?")
I think someone beat me to it, but you should chain together your if statements to make things flow better.
a = input("Question 1 ? ")
if a == "yes":
print("Consequence of yes to question 1")
elif a == "no":
print("Consequence of no to question 1")
else:
print('third statement')
b = input("Question 2 ?")
if b == "yes":
print("Consequence of yes to question 2")
elif b == "no":
print("Consequence of no to question 2")
else:
print('third statement')
Since you're starting out and this is a pretty common track for people here's another tidbit for funzies. with your strings you can use the.lower() to make your user inputs a little more uniform. There is a lot you can do with strings to get the input standardized and hopefully this gets you rolling a bit.
a = input("Question 1 ? ")
##input into lowercase
a = a.lower()
if a == "yes":
print("Consequence of yes to question 1")
elif a == "no":
print("Consequence of no to question 1")
else:
print('third statement')
b = input("Question 2 ?")
##input to lower case
b = b.lower()
if b == "yes":
print("Consequence of yes to question 2")
elif b == "no":
print("Consequence of no to question 2")
else:
print('third statement')
