CS152 standard answer in 2019, TAs' solution This is a naive python interpreter that supports:

None; True; False; return; break; continue; if; elif; else; while; and; or; not; def.

superlong int, double(16), bool, str and part of tuple.

notice that str + str, str * int and int * str are valid.

a chain of comparisons is avaliable.

in this version, the return value is a bool instead of what python returns

if...elif...elif...else...

while

positional assignment and default assignment are avaliable print(), int(), float(), str(), bool() are already defined
