python里list、array、set、tuple转换

list、array、set、tuple转换方式：

其中np是

import  numpy as np

list转array

a1 = np.array(l1)

array转list

l1 = a1.tolist()

list转set

s1 = set(l1)

set转list

l1 = list(s1)

list转tuple

t1 = tuple(l1)

tupel转list

l1 = list(t1)

array转set

s1 = set(a1)

set转array

a1 = np.array(s1)

array转tuple

t1 = tuple(a1)

tuple转array

a1 = np.array(t)

set转tuple

t1 = tuple(s1)

tuple转set

s1 = set(t1)
