Why is that so?

Question

Hi.
Why is

if num == 0 or num == 1 or num == 2 or num == 3 or num == 4 or num == 5 or num == 6 or num == 7:
print(fruits[num])
else:
print("Wrong number")

working fine, of course - but looks stupid and

if num < 0 or num > 7:
print(fruits[num])
else:
print("Wrong number")

Is not working? Anyone have a glue?

Answer 1

1. There is an indentation missing.
2. The condition in the if clauses of the two codes are not equivalent. They're actually exact opposites.

I have a glue.

If num > 7 or num < 0 then how index can be exist in list?

Read this: If n< 0 or n>7 (the index of last fruit ), the program outputs "Wrong number".

You have printed opposite value. It should be:

if num < 0 or num > 7:
print ("Wrong number")
else:
print (fruits [num])
