python - My game keeps calling a method for the wrong sprite -

when try run game code tries run method wrong sprite. think line "player.handle_keys()" problem when run it, says can't find "handle_keys()" method "meteor" class. haven't got line run "meteor.handle_keys()" class should not have method.

here code:

you overriding player in loop

# check list of collisions. player in blocks_hit_list:     score +=1     print(score) 

change else , good

# check list of collisions. something_else in blocks_hit_list:     score +=1     print(score)
