Write a code block to encode strings from original messages, using our custom encoding. To do so: Initialize a variable called custom_encoded as an empty string Use a for loop to loop across all characters of a presumed string variable called custom_message Inside the loop, check if the current character is in the custom_encodings dictionary If it is, use the current char to get the value from custom_encodings, and concatenate it to custom_encoded The line inside the if should look something like out = out + dictionary[char] Otherwise, concatenate the current character to custom_encoded

custom_encoded = "" custom_message = "this is a pen" custom_encoding = { "a": "1", "e": "2", "i": "3", "o": "4", "u": "5" } for c in custom_message: if (c in custom_encoding) : custom_encoded = custom_encoded + custom_encoding[c] else: custom_encoded = custom_encoded + c print (custom_encoded)

Explanation:

The solution code is written in Python 3.

Let's define a variable custom_encoded with an empty string (Line 1).

Create another variable custom_message and set a sample string to it (Line 2).

Create one more variable custom_encoding to hold the mapping values between vowel and their respective encoded character (Line 3-9).

Create a for loop to loop through all the character in custom_message (Line 11) and in the loop check if the current character is found in custom_encoding dictionary, if so, use the current character to loop up the dictionary for the encoded value and add the encoded string to custom_encoded (Line 12-13). Otherwise, just add the current character to custom_encoded (Line 14-15).

At the end, print the custom_encoded to terminal and you shall get th3s 3s 1 p2n
