考了最简单的编程题， 我记错了点， a,b 那个不会会报错：太多返回值， 方法只返回tuple或者解包 >>> def aa(): ... return 1,2,3 ... >>> a = aa() >>> print(a) (1, 2, 3) >>> a , b = aa() Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: too many values to unpack (expected 2) >>> >>> a,b = aa() Traceback (most recent call last): File "<stdin>", line 1, in <module> ValueError: too many values to unpack (expected 2) >>> a,b,c = aa() >>> print(a,b,c) 1 2 3 >>>
