You haven't converted to int. Use the same pattern
you use in the next line.

Your print is still trying to print the boolean result of the expression

income - cost == profit

And you have not defined profit yet so this will
yield errors if it ever gets this far.

The else syntax is simply

else:
   # code here that gets executed when the preceding if fails
   # You cannot have an expression with a colon on its own.
   # That's invalid Python.


> ?? ?? ?? ?? print (cost - income == loss)

Same as above you are trying to print the boolean expression result.

You probably want to add a string here like:

print ("cost - income ==", cost-income)


Or on two lines:

loss = cost-income
print(loss)

This is a text only list so binary attachments get stripped out.
You need to paste the full error text into the mail message.
Starting with the line:

Traceback (most recent call last):
...

I can't see the colours but expect it is that else statement
 - or more precisely the expression following it.
