dictionary = { 1:"integer", 2.03:"Decimal", "Lion":"Animal"} In the above dictionary: “integer” is a value of key “1” “Decimal” is a value of key “2.03” “Animal” is a value of key “Lion” Different ways to initialize a Python dictionary We can define or initialize ...
Python data type. It is a sequence of key-value pairs, where each key is unique and maps to a value. Dictionaries are mutable objects, meaning you can change their content without changing their identity. However, dictionary keys are immutable and need to be unique within each dictionary. Th...
In Python, dictionary data types are used to store data collection in key-value syntax. Every key in the dictionary has a unique value that can be accessed in a program using the specified key name. Python offers various methods to apply some operations on the keys of a dictionary. ...
