Before we sort the array, we’ll first need to create the array. To do this, we’re going touse the np.array function. The np.array function will enable us to create a NumPy array object from a Python list of 5 numbers: simple_array_1d = np.array([5,3,1,2,4]) And we can ...
import numpy as np # Generate a large 1D NumPy array with random integers large_array = np.random.randint(1, 10000, size=10000) # Function to sort the array using a for loop (bubble sort for simplicity) def sort_with_loop(arr): arr_copy = arr.copy() n = len(ar...
import numpy as np x = np.array([1,3,5,7,9]) z = x > 5 z np.where(z,x,5) 结果如下:【下面截图错误,大家自行练习】 例二:查找数组中大于18岁的人,并返回它们的下标; y = np.array([19,35,15,25,10]) y z = y > 18 z np.where(z) 结果如下: np.cumsum()和np.cumprod() ...
a = np.array([1, 2, 6, 4, 2, 3, 2]) u, indices = np.unique(a, return_inverse=True) indices 2、布尔运算 numpy.in1d()测试ar1中的数组元素是否在ar2中,返回布尔值 numpy.in1d(ar1, ar2, assume_unique=False, invert=False) # numpy.in1d()实例化 import numpy as np test = np....
