Tell us what’s happening:

error call in console is:
Traceback (most recent call last):
File “main.py”, line 98
SyntaxError: ‘return’ outside function
I recognize return is inside the function but the code does not pass. Please help.

Your code so far

First of all you have a duplicated line here. Is there some reason for that?

Next, if return was inside the function, you would not get this error message.

What makes you say that?

3

Retuen is lined up further right to the previous call.

4

Doesn’t work like that. Once the indentation is finished, the function is finished.

Reset the step. Here is the original indentation of the code

def validate(data):
    is_sequence = isinstance(data, (list, tuple))
    ...
    ...
        invalid_records = find_invalid_records(**dictionary)
        
    if is_invalid:
        return False
    print('Valid format.')
    return True

It should all be indented to be part of the function.

If you change the indentation, and move it back to the left margin, then the function code block is finished.

def function():
    code
    code

code # not in function
    return #not in function

Thanks Code passed. now

Ok great! As always, please ask if you have a question about something

Sorry when I submit , it went back to errors.

for index, key in enumerate(invalid_records):

val = dictionary[key]

print(f"Unexpected format ‘{key}: {val}’ at position {index} ")

is_invalid = True

if is_invalid:

Pass

return True

print(‘Valid format.’)

return True

indentation error after return. error after return

validate(mediccal_records)
