df.set_index=("Neighbourhood",inplace=True) giving me SyntaxError: invalid syntax
set_index is a function, you need to call it.
try df.set_index("Neighbourhood",inplace=True) (without the =)
All of my previous code runs well. 
It is only when I try to set the index to a particular column as the code below shows, that I run into an error. 
Honestly - this same method has worked before and I have not been able to find any other method to do the same thing. 
df.set_index=("Neighbourhood",inplace=True)
