在Python中从2个一维数组创建二维数组

# 假设我们有两个一维数组
array1 = [1, 2, 3]
array2 = ['a', 'b', 'c']

# 使用列表推导式创建二维数组
two_dim_array = [[array1[i], array2[i]] for i in range(len(array1))]

print(two_dim_array)

[[1, 'a'], [2, 'b'], [3, 'c']]

# 假设我们有两个一维数组
array1 = [1, 2, 3]
array2 = ['a', 'b', 'c']

# 使用zip函数和列表推导式创建二维数组
two_dim_array = [list(pair) for pair in zip(array1, array2)]

print(two_dim_array)

[[1, 'a'], [2, 'b'], [3, 'c']]

import numpy as np

# 假设我们有两个一维数组
array1 = [1, 2, 3]
array2 = ['a', 'b', 'c']

# 使用numpy创建二维数组
two_dim_array = np.column_stack((array1, array2))

print(two_dim_array)

[[1 'a']
 [2 'b']
 [3 'c']]

from itertools import zip_longest

array1 = [1, 2, 3, 4]
array2 = ['a', 'b', 'c']

# 使用zip_longest确保即使数组长度不一致也能正确处理
two_dim_array = [list(pair) for pair in zip_longest(array1, array2, fillvalue=None)]

print(two_dim_array)

[[1, 'a'], [2, 'b'], [3, 'c'], [4, None]]
