Python functions can return values, which allows you to retrieve information or the result of a computation from the function. Sometimes, you may wantyour function to return a key-value pair, a common data structure used in Python dictionaries. Key-value pairs help link pieces of related inform...

In this case, we use the dict() function in conjunction with the zip() function to pair up elements from the keys and values lists to create a dictionary −Open Compiler keys = ["name", "age", "city"] values = ["Bob", 28, "Paris"] person_dict = dict(zip(keys, values)) ...
In general, a function takes arguments (if any), performs some operations, and returns a value (or object). The value that a function returns to the caller is generally known as the function’s return value. All Python functions have a return value, either explicit or implicit. You’ll ...
