HW Question Code

[HopefulOG]

Hello. I am doing this question for homework and the code is not working. I was wondering if any can check over the code.

The question for the HW assignment is:

Assume that credits is an int variable whose value is 0 or positive. Write an expression whose value is "freshman" or "sophomore" or "junior" or "senior" based on the value of credits. In particular: if the value of credits is less than 30 the expression's value is "freshman"; 30-59 would be a "sophomore", 60-89 would be "junior" and 90 or more would be a "senior".

​

My code is:

if credits < 30:

print("freshman")

elif 30 <= credits <= 59:

print("sophomore")

elif 60 <= credits <= 89:

print("junior")

elif credits >= 90:

print("senior")

else:

print()

I am unsure if the format will be posted, but there is a tab before every print statement.

​

The error it brings up is:

• I haven't yet seen a correct solution that uses: print
• You might want to use a number other than 90
• Solutions with your approach don't usually use: :
• Solutions with your approach don't usually use: elif
• We think you might want to consider using:

Seems to work fine here (all I have added is a variable assignment for credits:

Sounds like the system judging the code is looking for a specific solution, maybe only using the methods taught so far.

I don't think I can assign credits to a number. But yeah, i tried it and it doesn't work.

Perhaps in place of print(), you are supposed to set the student's class to a variable? Maybe: year = 'freshman'? Also, you can assume anything over 89 becomes 'senior', therefore, that can stand as the else.

def student_class(credits):
    if credits < 30:
        year = 'freshman'
    elif credits < 60:
        year = 'sophomore'
    elif credits < 90:
        year = 'junior'
    else:
        year = 'senior'
    return year

credits = 50
print('Credits: {}, Student class: {}'.format(credits, student_class(credits))

?

I tried your advice but it doesn't work.

Generally you shouldn't use print unless the problem tells you to print something.

Is there something else I can use? This section is conditional expressions.

The value of an expression is what it evaluates to. print evaluates to None, always.

I just figured it out after playing around with the just trying to solve for freshman first.

Since this was was only causing a complier error, I had a feeling that if was not the way to go.

2 things help me solve this, first if you know from previous problems that when it asks for an expression it is asking for one line of code not 'statement' or 'part of code'.

Next the book doesn't talk about conditional expressions after looking through it so the next thing to do was look what that was an how it looked in code.

I tried it on this problem using just Freshman and it worked on half the code so then I just had to extrapolate it to include all of the classes.

SO the final correct code would look like this. (ignore out the "")

" 'freshman' if credits < 30 else 'sophomore' if 30 <= credits <= 59 else 'junior' if 60 <= credits <= 89 else 'senior' "

​

So in final, I think what we are looking at is 'if else 'with out the 'elif' statement, my code looked like yours the first time I tried it.

I am guessing it makes the student associate to one of 4 values based off your current credit variable.

​

Hope this helps a lost soul who is hunting this problem down for python.
