python中三维数组的输入

Question

我对用python编写代码很陌生，我想知道是否有什么方法可以将C语言中的代码转录成python：

for (K=1; K<3; K++)
    for (I=0; I<3; I++)
        for (J=0; J<7; J++){
            printf("Year: %d\tProvince: %d\tMonth: %d: ", K, I, J);
            scanf("%f", &A[I][J][K]);
        }

到目前为止，我只做了这些，唯一缺少的是如何在三维数组中输入数据

for k in range(1,3):
    for i in range(1,3):
        for j in range(1,7):
            print("Year: " + str(k) + " Province: " + str(i) + " Month: " + str(j) + ": ")

Answer 1

如果您只想在标准、本机python中实现这一点，应该可以：

import pprint # To display "3d array" in a recognizable format 
A = [[[0 for _ in range(2)] for _ in range(2)] for _ in range(6)]

for k in range(2):
    for i in range(2):
        for j in range(6):
            print("Year: {0} Province: {1} Month: {2}".format(k,i,j))
            A[j][i][k] = raw_input()

pprint.pprint(A) # for an easy to read 2x2x6 format display

输入一些数字（如1-24）后，给出输出：

[[['1', '13'], ['7', '19']],  
[['2', '14'], ['8', '20']],  
[['3', '15'], ['9', '21']],  
[['4', '16'], ['10', '22']],  
[['5', '17'], ['11', '23']],  
[['6', '18'], ['12', '24']]]  

Answer 2

你可以用numpy。示例假设您需要float64s.change type add needed

import numpy as np

arr = np.empty([2, 2, 6], np.float64)
for k in range(2):
    for i in range(2):
        for j in range(6):
            print("Year: " + str(k) + " Province: " + str(i) + " Month: " + str(j) + ": ")
            arr[k][i][j] = np.float64(raw_input())
