matlab中利用

a = [1,2,3,5,2,4,0]

[v,i]=max(a)即可找出最大值和最大值的位置，请问python中如何转化？

v,i=a.max()   ??? 好像不行啊？

在Python中这两个功能是分开的，求最值位置用a.argmax()

v, i = a.max(), a.argmax()

>>> a = [1,2,3,5,2,4,0]
>>> v, i = a.max(), a.argmax()
Traceback (most recent call last):
  File "<console>", line 1, in <module>
AttributeError: 'list' object has no attribute 'max'
>>> a = (1,2,3,5,2,4,0)
>>> v, i = a.max(), a.argmax()
Traceback (most recent call last):
  File "<console>", line 1, in <module>
AttributeError: 'tuple' object has no attribute 'max'

运算出错啊？？？

用numpy啊

你这个 a 赋值的是list ，没有max方法

a = np.array([1,2,3,4,5])

v, i = a.max(), a.argmax()

Ok, it works, thank everybody!
