We should publish some advice on creating content managers. I agree, I'm just not sure PEP 8 is the right place for it. PEP 8 seems like it is structured more as mechanical guidelines for the look and feel of code, not so much for the semantic content of the code.  As such,

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?
