[Python] How to be able to retry an input for a specific key in dictionary in Python without...

I'm trying to make a script that will ask for 5 score input from the user. Each score corresponds to a specific dilution. The input are strings and only six "characters" are allowed to be entered and q to quit the script and show each dilution with their score that have been entered. The problem is that when a invalid "character" is used it skips the dilution completely and does not add it to the dictionary and what I want is to retry the input for the specific dilution.

dil = ["1:16", "1:32", "1:64", "1:128", "1:256"]
corr_input = ["+", "++-", "-", "+-", "-a", "A"]
scores = {}

for dil in dil:
testscore = input("Enter score: ")
try:
if testscore in corr_input:
scores[dil] = testscore
elif testscore == "q":
print("Done!")
break
else:
print("Not a valid score!")
except TypeError:
print("Invalid input! Try again")
break
print(scores)


What I get!

#########
Enter score: +
Enter score: +
Enter score: v
Not a valid score!
Enter score: +
Enter score: +
{'1:16': '+', '1:32': '+', '1:128': '+', '1:256': '+'}`
