python - TypeError: unhashable type: 'list' (a few frames into program) -
so first project in python outside of code academy, decided make basic molecular dynamics simulator on pygame. works fine while, electrons start move fast, , strip other electrons off atoms, typeerror in title. have no idea comes from, , appears after program has been running long enough me mess physics.
now know error telling me i'm trying pass list somewhere shouldn't, i've looked on program , can't figure out where. error pops in bit tells electrons how orbit atom angle = finda(particles[el], particles[nuc]) + 0.001, controlled block of code near end tells program in order physics, , list of each electron meant orbit controlled point, , on.
so decided give code.

next time i'll stick print("hello, world!")
so, believe happening when execute line angle = finda(particles[el], particles[nuc]) + 0.001, either el variable or nuc variable list of sort, rather single object.
this throws error because particles dict, , cannot have list or mutable type key in dict.
so, given error not execute immediately, suspect somewhere along line, in piece of code not executed, accidentally passing in list of sort.
if did mean things in particles dict using list key, should convert list tuple first: tuples lists, immutable, , can hashed , used key of dict.
