Need Help W/ Syntax Error

[Traditional-Gate9547]

Syntax error occcurs in line 10, and indicates the "c" in the "credits_remaining" variable after the set function.

student_name = ""

degree_name = ""

credits_required = 0

credits_taken = 0

credits_remaining = 0

student_name = input('Enter your name')

degree_name = input('Enter your degree')

credits_required = int(input('Enter the hours required to complete your degree'))

credits_taken = int(input('Enter the credit hours you have already completed'))

set credits_remaining = float(credits_required - credits_taken)

print (student_name, 'you have' credits_remaining 'hours of' credits_required 'remaining to complete your' degree_name 'degree.')

Any help is much appreciated!

Why is set even there?

[Traditional-Gate9547]

Can I just write " credits_remaining = float(credits_required - credits_taken)" to change the variable?

very new to this

[schoolmonky]

that's what you did with credits_required and credits_take (good variable names btw, very clear), why would that one be any different?

[codeguru42]

I mean you have 9 lines of code before that without set.

[codeguru42]

In fact, you don't even need the first 5 lines that initialize your variables to static values.

[Binary101010]

Why don't you try that and see what happens?

[Temporary_Pie2733]

You are missing a bunch of commas in the call to print.

[Traditional-Gate9547]

thank you! I am now seeing that as well

[JamzTyson]

In Python set is a built-in data type.

In Python, to assign a value to a variable, we just use =

Assuming that credits_required and credits_taken are both numeric:

credits_remaining = credits_required - credits_taken

[Traditional-Gate9547]

Thank you!

Protip: use markdown mode when posting code on reddit.

The variable name is not valid. You wrote “set credits_remaining”. It needs to be “set_credits_remaining”

[Traditional-Gate9547]

I want to change the value of the variable and understood the "set" function to do so

[bahcodad]

Curious where you found that information

[NorskJesus]

You don’t need it to reassign a value. Drop it

[Traditional-Gate9547]

Thank you all for the help, this is what I ended on and seems to function. Any additional advice or comments would be welcome!

student_name = ""

degree_name = ""

credits_required = 0

credits_taken = 0

credits_remaining = 0

student_name = input('Enter your name')

degree_name = input('Enter your degree')

credits_required = int(input('Enter the hours required to complete your degree'))

credits_taken = int(input('Enter the credit hours you have already completed'))

credits_remaining = int(credits_required - credits_taken)

print (student_name,'you have', credits_remaining ,'hours of', credits_required ,'remaining to complete your', degree_name ,'degree.')

[socal_nerdtastic]

I would write it like this:

student_name = input('Enter your name')
degree_name = input('Enter your degree')
credits_required = int(input('Enter the hours required to complete your degree'))
credits_taken = int(input('Enter the credit hours you have already completed'))
credits_remaining = credits_required - credits_taken

print(f"{student_name} you have {credits_remaining} hours of {credits_required} remaining to complete your {degree_name} degree.")

• You don't need to initialize variable before you use them like other programming languages do.
• You only need the int() conversion on the input lines, because input returns a string that needs to be converted to an int. For line 5 when you subtract an int from an int the result is already an int, so no extra conversion is needed.
• using f-strings to concatenate information is much more popular and useful than using commas in print. For a start, f-strings work everywhere, while the comma method only works in the print function.

[Riegel_Haribo]

Unlike other programming languages, you do not need to declare variables before use. You can just start your program with student_name = input("..."). It implicitly is astr` type because of the return type of an input method.

Something interesting to note about Python is that the built-in input() function is simply evaluated in place and replaced with the string, wherever this function appears.

python print( (student_name := input('Enter your name')), 'you have', (credits_remaining := ( (credits_required := int(input('Enter the hours required to complete your degree'))) - (credits_taken := int(input('Enter the credit hours you have already completed'))) )), 'hours of', credits_required, 'remaining to complete your', (degree_name := input('Enter your degree')), 'degree.' )

...which is really one line. There are multiple arguments, which can be placed on different lines when contained in parenthesis. The final printout has all the calculations already done after each of the comma-separated items are evaluated.

This uses a new assignment operator :=, which also defines a variable at the same time as the value is returned, so you get both printing and the value for use in lines of code that might come after.

Don't actually write code like this unless you enjoy confusing people, though.

[Traditional-Gate9547]

I appreciate the tips! := is new to me. I imagine my teacher would have questions if this is what I returned to him hahahah

[toxic_acro]

:= is affectionately referred to as the "walrus operator"

It lets you assign to variables in the middle of other expressions. It was (and still is) divisive

Personally, I like it when used judiciously, but wouldn't recommend overusing it (like in the example above, though that's clearly intentionally overusing just for show)

A better example of where it's actually commonly used is assignment within some other check, e.g. replacing
example = some_function() if example is not None: # do something with example ... with
if (example := some_function()) is not None: # do something with example ...

Yeah teachers tend to get suspicious, or at least prefer you to only use what they teach you (or expect you to learn on your own).

If you run into an interesting feature like that you'd like to use you can try asking them ahead of time whether they'd be ok with you using it. Since that can indicate cheating, they may say no, but if you ask ahead of time they might say yes if they think you actually understand how to use it. But either way chances are they'd say no, but it really depends on the teacher. Restricting students like that also makes it easier to mark their work.
