Part of the problem with the above is that the double quotes don't need
to be backslash-escaped.  I don't do any Python programming, so I'm not
entirely sure how to improve these, but I've made an attempt (note that
it'll only work with nano 1.3.x because of the "icolor" directive):

syntax "python" "\.py$"
icolor brightblue "def [A-Z_0-9]+"
color brightcyan 
"\<(and|assert|break|class|continue|def|del|elif|else|except|exec|finally|for|from|global|if|import|in|is|lambda|map|not|or|pass|print|raise|return|try|while)\>"
color brightgreen "(["']).*[^\\]\1"
color brightgreen start="("""|''')" end="("""|''')"
color brightred "#.*$"
