do we edit the code that is already written or type it out in our own workspace?

when i attempt to add changes to the code, it doesn't allow me to make any.

errors.py 
print("Hello")
print(name)

print("Let's do some math!")
print(5 + "a")

print("Thanks for playing along!')

You should be able to place the cursor into the black background buffer and edit the existing code.

Try reloading the page. Maybe it didn't load completely.

thanx buddy! you were right..it was just buggy lol. One more quick question for ya if not too much to ask! Still on python but a bit further.. I am supposed to add two variables together to equal a "total" then print the total

EX: 

current_count = 14
planned = 5
upcoming_releases = 2
del planned
total = "current_count"+"upcoming_releases"

# (the bottom line is how i thought it would be done, followed by):

print(total)

but it states it is wrong..i have been trying to figure this out for 20min, could you possibly point me in the direction of what i am doing wrong here please?

Your current line is appending two strings:

$ python3
Python 3.4.3 (default, Oct 14 2015, 20:28:29) 
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> 
>>> total = "current_count"+"upcoming_releases"
>>> total
'current_countupcoming_releases'

You need to remove the quotation marks to reference the variable names:

>>> current_count = 14
>>> upcoming_releases = 2
>>> total = current_count + upcoming_releases
>>> total
16
