How to Spell out Number Using Dictionary in Python

Here is a Python program that spells out a number using a dictionary.

How it works is – if you enter numeric ‘1’, it displays ‘one’ as a character.

Python supports three types of compound data types.

Those are List, Tuple, and Dictionary. Out of these, I used a dictionary-type to achieve this.

What is python dictionary?

You can create an empty dictionary with empty curling braces. It supports data of type key/value pairs.

my_dictionary = {}

Here is a dictionary with data of two key-value pairs.

my_dictionary = {"name" : "Srini", "age" : 20}

Further to, you can get data from a dictionary by giving the key value.

my_dictionary["name"] ==> it will display Srini

Here is screen shot of the results

As said, with the key, you can print its value. The same concept I used to write the program.

Here is python logic to spell out a number

#!/usr/bin/python3
## This program spells out the number
my_input = input("Enter number from 1 to 4: ")
my_dict_mapping = {
    
    "1" : "One",
    "2" : "Two",
    "3" : "Three",
    "4" : "Four"
}
for i in my_dict_mapping:
    if i == my_input:   
        print (my_dict_mapping[i])
        break
    else:
        print ("Mind your entry!!")
