A dictionary is a pre-built data structure in Python that holds a set of key-value pairs. Each key is associated with a value, and you can use the key to access the corresponding value.
In Python, dictionaries can be used inside functions like any other data type. You can also modify a dictionary inside a function by adding, removing, or updating items. It's important to note that when passing a dictionary to a function, it will be passed by reference, not by value, so any changes made to the dictionary inside the function will affect the original dictionary.
You may traverse through the key-value pairs using a "for" loop and the "items()" function.
- for loop: Python's for loop is a control structure that enables you to repeatedly iterate over a series of items, such as a list, a tuple, a string, or a range, and to run a block of code for each one of them.
- items(): The items() method is a built-in method of dictionaries in Python that returns a view object containing the key-value pairs of the dictionary as tuples.
Please check the code below to use the dictionaries inside a function in Python.
