The numpy.insert() function is used to insert values along the given axis before the given indices.The function can be used to insert a single value or multiple values into an existing array. The function also provides the option to insert values at specific locations within the array....

It’s also possible to use the same function to generate a 2d array of random numbers. 也可以使用相同的函数生成随机数的2d数组。 In this case, inside the parentheses we need to insert as a tuple the dimensions of that array. 在本例中,我们需要在括号内插入该数组的维度作为元组。 The first...

Many of the examples in this tutorial useawkward0.fromiterto make Awkward Arrays from lists andarray.tolist()to turn them back into lists (or dicts forTable, tuples forTablewith anonymous fields, Python objects forObjectArrays, etc.). These should be considered slow methods, since Python inst...
