Copypasting the solution to part 3 of this excercise produces this error: {“passed”: false, “errorMessage”: “invalid syntax (. My own solution was basically the same but with some extra spaces after the ‘:’ and such. All previous parts have been passed and i tried re-running all the cells. Also, it does seem to produce the right output in the notebook, so it’s just the “test work” step that fails.

The code currently looks like this:

## YOUR SOLUTION HERE ##

# rename Location_EUROPE
dfs[3] = dfs[3].rename({'Location_EUROPE':'Location'},axis=1)

# re-do the concatenation to generate full_df
full_df = pd.concat(dfs)

#show output
full_df.head()

Is this a bug or am i missing something?
