if控制流语句执行条件原理

if cars > people: print(“We should take the cars.”) elif cars < people: print(“We should not take the cars.”) else: print(“We can’t dicide.”)

if buses > cars: print “That’s too many buses.” elif buses < cars: print(“Maybe we could take the buses.”) else: print(“We still can’t decide.”)

if people > buses: print(“Alright, let’s just take the buses.”) else: print(“Fine, let’s stay home then.”)
