Tosolve the duplicate keys issue,we canpass a merge function to thetoMap()methodas the third parameter to handle the values associated with the duplicate keys. We may have different merge requirements for the duplicate keys scenario. In our example, we would like topick the higher score once ...
The apply() method is a part of concat() function's prototype that calls the function with a given this value, and arguments provided as an array.Alternatively, you could use the ES6 syntax to make the above example super concise:
How do you flatten array in javascript If you are given an array that contains literals, arrays and objects and you want to get all the values to one array. Here is the snippet using recursive function to attain that. functionimplode(arr){varres = [];for(vari =0; i < arr.length ;...

This function returns a one-dimensional numpy array which contains all the elements of the input array in the specified order.Example 1Following is the example of Numpy ndarray.flatten() method which shows flattening a 2D array into a 1D array in the default row-major order, resulting in [1...
NumPy Array | Flatten only some dimensions: In this tutorial, we will learn how to flatten only some dimensions of a NumPy array with the help of an example.
In the example above, we’ve recycled one of the flatten() examples, but instead we’re using the flatMap() function to arrive at the same result.As it’s visible here, the flatMap() function not only flattens the nested collection, but gets an additional oportunity to add a ...
# Python program to flatten Nested Tuple # Recursive function to flatten nested tuples def flattenRec(nestedTuple): if isinstance(nestedTuple, tuple) and len(nestedTuple) == 2 and not isinstance(nestedTuple[0], tuple): flattenTuple = [nestedTuple] return tuple(flattenTuple) flattenTuple = [...
In this example a nested JSON data is converted into a Pandas DataFrame using the json_normalize() method and represented as a flat table.Open Compiler import pandas as pd # Sample nested JSON data data = [ {"person_id": 1, "Details": {"name": "Kiran", "age": 18, "gender": '...
