MongoDB's dynamic schema design enables you to add or modify fields without requiring all documents to have the same structure. If we insert item_3 again, MongoDB will insert a new document, with a new _id value. However, the first two inserts will throw an error because of the _id ...
two-dimensional data structure in computer programming languages, similar to an Excel table. In Python, a DataFrame is an object in thepandaslibrary. The pandas library is a core library used by Python in Excel, and DataFrame objects are a key structure for analyzing data with Python in Excel...
A stack is a useful data structure in programming. It is just like a pile of plates kept on top of each other. In this tutorial, you will understand the working of Stack and it's implementations in Python, Java, C, and C++.
