返回多值函数可以返回多个值吗?答案是肯定的.比如在游戏中经常需要从一个点移动到另一个点,给出坐标.位移和角度,就可以计算出新的坐标:# math包提供了sin()和 cos()函数,我们先用import引用它: import math def move(x, y, step, angle): nx = x + step * math.cos(angle) ny = y - step * math.sin(angle) return nx, ny print(move(100, 100, 60,
#定义函数 def Get_Counter_AllMeasureValue(self, inst_dg_address): """ get all measure value ,as Frequency,period,duty,+width,-width,and so on... :param inst_dg_address: :return: Frequency,period,duty,+width,-width :return: all return value is s
函数返回值 多条return语句: def guess(x): if x > 3: return "> 3" else: return "<= 3" def showplus(x): print(x) return x + 1 return x + 2 #执行结果 10 11 #从结果来看 出现第一个return后 下面的就不会执行 def fn(x): for i in range(x): if i > 3: return i else:
def hi(name="yasoob"): def greet(): return "now you are in the greet() function" def welcome(): return "now you are in the welcome() function" if name == "yasoob": return greet else: return welcome a = hi() print(a(
