In the next line, numpy.insert() function is used to insert the value 4 at index 2 of the flattened 'x' array. This results in a new flattened array with the value 4 inserted at the 2nd index. In the third line, np.insert() function is used to insert the value 4 in the second...

In the following example we have created an array of int datatype, where we try to insert float value −Open Compiler import array as arr #Creating an array my_array2 = arr.array('i',[11,340,30,40]) #Printing the elements of an array print("Array Elements Before Inserting : ", ...
value: int, Series, or array-like # 整数、Series或者数组型数据。是插入列的值 allow_duplicates: bool, optional # 布尔型数据, 可选参数。如果某个列名在dataframe中已经存在,将allow_duplicates置为true才可以将同样的列名插入 示例 1. 原始数据 import pandas as pd import numpy as np df = pd.DataFra...
