def exchange(a,b): a,b = b,a return (a,b) x = 10 y = 20 x,y = exchange(x,y) print(x,y)
举一反三
- def exchange(a,b): a,b = b,a return (a,b)x = 10y = 20x,y = exchange(x,y)print(x,y) A: 20,10 B: 20 20 C: 10 10 D: 20 10
- 下面代码的输出结果是( ).def exchange(a, b):a, b = b, areturn(a,b)x = 10y = 20x, y = exchange(x, y)print(x, y) A: 20 10 B: 20,10 C: 10 10 D: 20 20
- 下面代码的输出结果是 def exchange(a,b): a,b = b,a return (a,b) x = 10 y = 20 x,y = exchange(x,y) print(x,y) A: 20 10 B: 20 20 C: 10 20 D: 10 10
- 下面代码的执行结果是def exchange(a,b): a,b = b,a return (a,b)x = 10y = 20x,y = exchange(x,y)print(exchange(x,y)) A: (10, 20) B: (20, 10) C: 10, 20 D: 20, 10
- 写出下面代码的运行结果( )def exchange(a,b): return (b,a)x = 10y = 20x,y = exchange(x,y)print((x,y)) A: 10 20 B: 20 10 C: (20, 10) D: (10, 20)
