Tell us what’s happening:

I’m able to get expected output when I try it on idle, but it doesn’t pass the test cases from 16th one. Need help in finding the error, if I’m overlooking.
Thanks

Your code so far

open the browser console, there is extra output there when you run the tests, for example:

AssertionError: '****[76 chars]gs, bac -45.67\nTransfer to Entertainme -20.00\nTotal:  834.33' 
             != '****[76 chars]gs, bac -45.67\nTransfer to Entertainme -20.00\nTotal: 834.33'

the first is your code, the second is the expected, notice where there is a difference

I have corrected 16th test case, but now I couldn’t figure it out why 19,20 and 24 are failing. I presume create_spend_chart is giving expected output string when I check with print statement.

4

if you open the browser console the tests output there similar messages for all the failed tests, you should be able to find them yourself

otherwise, I will need to be at my pc to do the same

Please share your updated code

Thanks everyone, I was able to pass the all the test cases.
Thanks again.
