Python |将 Numpy 数组转换为元组
原文:https://www . geeksforgeeks . org/python-convert-numpy-arrays-to-tuples/
给定一个 numpy 数组，编写一个程序将 numpy 数组转换成元组。 示例–
Input: ([[1, 0, 0, 1, 0], [1, 2, 0, 0, 1]])
Output: ((1, 0, 0, 1, 0), (1, 2, 0, 0, 1))
Input: ([['manjeet', 'akshat'], ['nikhil', 'akash']])
Output: (('manjeet', 'akshat'), ('nikhil', 'akash'))
下面给出了将 numpy 数组转换为元组的各种方法。 方法#1:使用元组和映射

# Python code to demonstrate
# deletion of columns from numpy array
import numpy as np
# initialising numpy array
ini_array = np.array([['manjeet', 'akshat'], ['nikhil', 'akash']])
# convert numpy arrays into tuples
result = tuple(map(tuple, ini_array))
# print result
print ("Resultant Array :"+str(result))
输出:
Result:(('manjeet', 'akshat'), ('nikhil', 'akash'))
方法 2:使用天真方法

# Python code to demonstrate
# deletion of columns from numpy array
import numpy as np
# initialising numpy array
ini_array = np.array([['manjeet', 'akshat'], ['nikhil', 'akash']])
# convert numpy arrays into tuples
result = tuple([tuple(row) for row in ini_array])
# print result
print ("Result:"+str(result))
输出:
Result:(('manjeet', 'akshat'), ('nikhil', 'akash'))
