Python zip

 

 

import numpy as np

letters = ['a', 'b', 'c']
nums = [1, 2, 3]


for letter, num in zip(letters, nums):
     print("{}: {}".format(letter, num))


# 将多个list的数据组合成tuple的list
# 得到: [(4, 1), (5, 2), (6, 3)].
# 相当于通过两个数组，组合成了一个矩阵
arr=list(zip([4, 5, 6], [1, 2, 3]))


res = np.array([[3,4,5], [6,7,8]])
loc = np.where(res >= 0.1)
print(loc)
print(type(loc))

for pt in zip(*arr[::-1]):
    print('----------------')
    print(pt)
    print(pt[0])
    print(pt[1])
