A dictionary is a pre-built data structure in Python that holds a set of key-value pairs. A Python dictionary's keys must be distinct, unchangeable, and of a hashable data type (such as strings, numbers, or tuples). A dictionary's values can be replicated and of any data type.  


In a Python dictionary, a key value pair consists of a unique key, which acts as an identifier for an item in the dictionary, and the value, which is the data associated with that key. The keys in a Python dictionary must be unique and immutable.  

There are a few ways to print specific key-values from a dictionary in Python:  

  • Using the key in square brackets [].  
  • Using the “get()” method.  
  • get(): This method takes in one argument, which is the key for which the value is to be retrieved. The get() function delivers a default value supplied as the second parameter to the method if the key cannot be located in the dictionary. If no default value is specified and the key is not found, the get() method returns None.  
  • Using a for a loop.  


You may have a look at the code given below for printing specific key value from a dictionary.

Dependent Libraries : 
import itertools
keys=[1,2,2,3,2,3]
values=['apple','book','pen','soccer','paper','tennis']
final_data = {a:[i[0] for i in b] for a, b in [(a, list(b)) for a, b in itertools.groupby(sorted(zip(values, keys), key=lambda x:x[-1]), key=lambda x:x[-1])]}

{1: ['apple'], 2: ['book', 'pen', 'paper'], 3: ['soccer', 'tennis']}

Instructions

Follow the steps carefully to get the output easily.

  1. Download and install Pycharm Community edition on your desktop.
  2. Open new python file in your IDE.
  3. Copy the snippet using the 'copy' and paste(till line no 4) it in your python file.
  4. Add print statement to the end.(print(final_data))
  5. Run the file to generate the output.
