Clash Royale CLAN TAG#URR8PPPTuples, dictionary, and helper function problems in Python
So I had an assignment where I took a list of tuples as an argument such as,
[('A', 3), ('C', 4), ('B', 2), ('P', 4)]
and I had to compute the overall gpa which is basically((letter-grade-number * number of credits) / number of credits). So I had to use a dictionary and my body was composed of 3 parts. The first used a helper function that appended the unweighted grades to a list and used a counter to keep track of all the credits that were taken, the second part was a conditional that returned -1 if all the lists were not considered for grading and the last part finally summed all the values in the appended list and divided it by the total number of credits taken and it works perfectly.
((letter-grade-number * number of credits) / number of credits)
-1
Now, my next assignment takes a string as an argument such as:
'Jane A 3 A- 3 F 1#Bob C+ 2 D+ 3 B+ 3#Chris C 4 C 3 C- 2#Susie F 2 NC 1'
I figured I can simply turn this string into a list of tuples however, once I convert the first iteration of the string (which is marked by the # sign in the parameter), it is
['Jane', 'A', '3', 'A-', 3, 'F', 1]
['Jane', 'A', '3', 'A-', 3, 'F', 1]
I used a helper function to slice the string, turn it to a list, take only the letter grades and integers and zipped it into a tuple. So my helper function converts the first iteration of my initial string into a tuple that my previous code takes in its parameter:
[('A', 3), ('A-', 3), ('F', 1)]
[('A', 3), ('A-', 3), ('F', 1)]
When I input that tuple in my previous code, it gives me the right answer, however, when I try to call it after my first helper function returns the tuple, I get an iteration error.
My code is quite long, about 60 lines and I do not think I am allowed to post it here so if anyone is willing to take a look, here is my pastebin --- https://pastebin.com/3kG7WXAp

Including the stack trace of your error can also be helpful, in addition to cutting down to a MCV example as mentioned by others.

I didn't know I pasted my code on the post. I thought I put a link to my code using pastebin. I'm sorry.

Dunno if it fixes all you problems, but it fixed the errors you had:
weight = float(key1) * float(tup_val)
and
numbers_of_credit += float(i[1])
