In Python, the|(pipe) operator, also known as the union operator, provides a concise and intuitive way to add a dictionary to another dictionary. This operator performs a union operation on the dictionaries, merging their key-value pairs into a new dictionary. ...
Python dictionariesare a built-indata typefor storingkey-value pairs. The dictionary elements are mutable and don't allow duplicates. Adding a new element appends it to the end, and in Python 3.7+, the elements are ordered. Depending on the desired result and given data, there are various ...

Without directlycreatingdictionaries, users can also use the “add and remove” approach that inserts and deletes elements tocreatea newdictionaryinPython....
Python provides various ways to add items or elements to a dictionary. Dictionaries are mutable, so we can add, delete, and update the dictionaries. In
Lastly, we shall have a look at the union operator( | )introduced in Python 3.9. This operator works on two dict object operands and returns the merged dictionary. Example: Merge Dictionaries using Union Operator >>>d1={'A1':20,'B1':25,'C1':40,'D1':50}>>>d2={"X1":100,"Y1"...
2. Using the|Operator (Python 3.9+) Python 3.9 introduced the merge operator|, which allows you to concatenate dictionaries in a single line. Syntax: Here is the syntax: dict3 = dict1 | dict2 Example: Now, let me show you a complete example. ...
