Write a NumPy program to convert a dictionary with numeric values to a NumPy array and print the array.Sample Solution:Python Code:import numpy as np # Initialize a dictionary with numeric values data_dict = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5} print("Original ...
# Converting the string dictionary to a Python dictionary t = literal_eval(udict) # Printing the original dictionary and its type print("\nOriginal dictionary:") print(t) print("Type: ", type(t)) # Creating a 2D NumPy array using dictionary comprehension result_nparra = np.array([[v[j...
Array Operations There are many Numpy operations that can be used to reduce a numpy array along an axis. python x = np.array([[1,2], [3,4], [5,6]]) # np.max operation print(np.max(x, axis = 1)) # [2 4 6] print(np.max(x, axis = 1).shape) # (3,) print(np.max...
#numpy import numpy as np a = np.array([1, 2, 3, 4]) # 创建的一维数组,参数为列表 np.shape(a) #(4,) b = np.array([[1,2,3,4],[4,5,6,7], [7,8,9,10]]) # 创建二维数组 np.shape(b) #查看数组的维度(以元组的形式输出) b.shape[0] # 返回二维数组的行数:3 b.shape...
