python - Return a string of country codes from an argument that is a string of prices -


so here's question:

write function return string of country codes argument string of prices (containing dollar amounts following country codes). function take argument string of prices following: "us$40, au$89, jp$200". in example, function return string "us, au, jp".

hint: may want break original string list, manipulate individual elements, make string again.

example:

> testequal(get_country_codes("nz$300, kr$1200, dk$5") > "nz, kr, dk"

as of now, i'm clueless how separate $ , numbers. i'm lost.

def test(string):     return ", ".join([item.split("$")[0] item in string.split(", ")])  string = "nz$300, kr$1200, dk$5" print test(string)
