I'd like to piggyback this thread for a situtation to consider in PEP 8.

PEP 8 suggests no extra spaces after and before square brackets, and
colons. So code like this is appropriate:

a_list[1:3]

But I find it less readable in the case of:

a_list[pos + 1:-1]

The colon is seemingly lost in the right.

Would it be better to read like below?

a_list[pos + 1 : -1]

Any opinion?
