I can't work out why this code is returning a "list index out of range error. Any suggestions ?

img = None
data_values = ['2', '3', '4', '5']
print("before condition: ", data_values, type(data_values), len(data_values))
try: if any(value in data_values for value in ('20', '42')) or (img is not None): print("after condition") form_data_values[f'{question}'] = form_data
except Exception as e: print(e)

here is the output of that code:

before condition: ['2', '3', '4', '5'] <class 'list'> 4
list index out of range
