[Tutor] 'int' object has no attribute 'items'

[Steven D'Aprano]

Hi Chidinma,

I'm afraid it is very difficult for me to understand your code, because 
your email program (Yahoo mail perhaps?) has mangled the code and put it 
all on one single line:

You may be able to prevent that by turning of "formatted text", or "rich 
text", or "HTML email", or whatever your email program calls this 
feature.

How are you running this? Python doesn't normally print "THERE IS AN 
ERROR/BUG IN YOUR CODE". My guess is that you are using one of the 
on-line Python courses where you type your code into the web page. Am I 
right? Which one?

That error doesn't seem to have anything to do with your code. Are you 
sure it is connected to the code you give above?

If you are using a website, it might be a bug in the website.

The first thing to confirm that dict_inp is a dict. Run:

print( isinstance(dict_inp, dict) )

just before that "for ..." line. If it prints True, then change the for 
line to:

    for k, v in dict_inp.items():

What happens then?
