Hi there! I’m getting an unexpected indent, however I didn’t change the template only the values
Can someone explain this to me? I am very confused.
The code doesn’t refresh when I start ‘15. The Big if’. Instead, the correct code from ‘14.I Got 99 Problems, But a Switch Ain’t One’ remains in script.py. In an effort to work around this I manually wrote the correct code. However, this error message keeps appearing… can anyone help?
I see this was posted a little while ago. Just in case you or anyone else has/is run into this issue:
You do not need to put a bool after the else in line 16. Your program is unable to understand your expression after the : . All other statements look correct. So your program will already be able to deduce that anything below 65 will register as a F.
Please let me know if I explained this correctly. It sounds right in my head.
I also felt the need to add the “and grade < 90”, “and grade < 80”, etc., because I thought
a grade of “75” might return a grade of C and D and F. But, it turns out that wasn’t necessary. Can someone explain why? Is Python just reading top-down, so once it assigns a value it doesn’t continue down the line to see what else might apply to it? I hope that makes sense.
If .. elif .. else statements are always top, down and only one branch can ever be followed (the one in which the condition is satisfied). If none of the branches are followed in the absence of an else clause, then nothing is returned from the function, otherwise the else clause is the default branch.
I found it simpler to start with the lowest value and gradually work up to the highest.
if x < 60: y = 'F'
elif x < 70: y = 'D'
elif x < 80: y = 'C'
elif x < 90: y = 'B'
else: y = 'A'
I don’t understand the comparators >= and <= what do they mean?
@mtf please reply.DON’T UNDERSTAND!
These operators represent either inequality, as in one value is different from the other, either greater than or less than, respectively, or they represent equality if both values are the same.
6 > 7 => False
6 >= 7 => False
6 < 7 => True
6 <= 7 => True
The above is rather moot, being literal. We’re more likely to be comparing two variables which may be dynamic in nature, or user input compared to a dynamic value or a static literal in the code.
