Python exercise using try/except with continue [closed]

Question

I can't figure out why my code doesn't work properly here, it seems to exit the for loop after the except: continue line. What do I do to fix this? (the code executes but the output is always -1 no matter what list/letter combination is fed so nothing is ever being added to the sum_total variable)

sample_list = [
  'Black Mirror', 
  'Breaking Bad', #2
  'Stranger Things', #6
  'The Leftovers', #2
  'How I Met Your Mother' #7  4.25
]
letter = 'e'
def find_average_first_index(input_list, input_letter):
  sum_total = 0
  for i in input_list:
    try:
      sum_total += input_list.index(input_letter)
      print(sum_total)
    **except:
      continue**
        
  if sum_total == 0:
    return -1
  else:
    average_value = (sum_total / len(input_list))
    return average_value

Answer 1

Here's fixed code:

def find_average_first_index(input_list, input_letter):
sum_total = 0
for i in input_list:
    try:
        sum_total += i.index(input_letter)
        print(sum_total)
    except ValueError as e:
        print(e)
        print(f"No {input_letter} in {i}")
        continue
    
if sum_total == 0:
    return -1
else:
    average_value = (sum_total / len(input_list))
    return average_value

Answer 2

Your code need to change like this

sample_list = [
   'Black Mirror',
   'Breaking Bad', #2
   'Stranger Things', #6
   'The Leftovers', #2
   'How I Met Your Mother' #7  4.25
]

letter = 'e'

def find_average_first_index(input_list, input_letter):

   sum_total = 0
   for i in input_list:
       try:
           sum_total += input_list.index(input_letter)
           print(sum_total)
       except:
           continue
       if sum_total == 0:
           return -1
       else:
           average_value = (sum_total / len(input_list))
           return average_value

find_average_first_index(sample_list,letter)

errors:-

1. You need to add try and except like this (if your code pattern is wrong you can see error messages; see: https://careerkarma.com/blog/python-break-and-continue/)

   try:
     sum_total += input_list.index(input_letter)
     print(sum_total)
   except:
     continue
   

2. find_average_first_index(sample_list,letter)

   run the code you need call function. (ref: https://www.w3schools.com/python/python_functions.asp)
