In python, implement multiplication of integer elements in a list or array elements in a list
1. Assuming that the elements in the list are integers, the following functions can be called:
def list_any_two_mul(mylist):
num = 1
temp = []
for i in mylist[:-1]:
([i * j for j in mylist[num:]])
num = num + 1
# Turn multiple lists into only one list results = [y for x in temp for y in x]
return results
Suppose there is a list mylist = [3, 5, 6, 8], and the above function is calledlist_any_two_mul(mylist) Then return [15, 18, 24, 30, 40, 48]
2. Assuming that the elements in the list are in an array form, the following functions can be called:
def list_any_two_and(mylist2):
temp2 = []
num2 = 1
# First, compare the elements in the list for i in mylist2[:-1]:
([cv2.bitwise_and(i, j) for j in mylist2[num2:]])
num2 = num2 + 1
# Put the results after the match in a list results2 = []
for i in range(len(temp2)):
for j in range(len(temp2[i])):
(temp2[i][j])
return results2
Verify the above functions, the elements are listed in the array, and then call the function. For specific implementations, please refer to the following code:
>>> import numpy as np
>>> a=(1,13).reshape(3,4)
>>> a
>>> array([[ 1, 2, 3, 4],
[ 5, 6, 7, 8],
[ 9, 10, 11, 12]])
>>> b=(13,25).reshape(3,4)
>>> b
>>> array([[13, 14, 15, 16],
[17, 18, 19, 20],
[21, 22, 23, 24]])
>>> c=(0,2,(3,4))
>>> c
>>> array([[0, 1, 1, 1],
[0, 0, 1, 1],
[0, 0, 1, 1]])
>>> d=[a,b,c]
>>> g=list_any_two_and(g)
>>> g
>>> [array([[1, 2, 3, 0],
[1, 2, 3, 0],
[1, 2, 3, 8]], dtype=int32), array([[0, 0, 1, 0],
[0, 0, 1, 0],
[0, 0, 1, 0]], dtype=int32), array([[0, 0, 1, 0],
[0, 0, 1, 0],
[0, 0, 1, 0]], dtype=int32)]This is the end of this article about Python's implementation of any two numbers in the list.
