Currently, we have following PEP: PEP 8: E114 indentation is not a multiple of 4 (comment)
However, I wonder how many people are using 2 spaces as their code indentation in projects? Should it be nesserary for us to change this PEP from “multiple of 4” to “multiple of 2”? -- https://mail.python.org/mailman/listinfo/python-list
