Question

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

Answer 1

Answer:

1. custom_encoded = ""
2. custom_message = "this is a pen"
3. custom_encoding = {
4.    "a": "1",
5.    "e": "2",
6.    "i": "3",
7.    "o": "4",
8.    "u": "5"
9. }
11. for c in custom_message:
12.    if(c in custom_encoding):
13.        custom_encoded = custom_encoded + custom_encoding[c]
14.    else:
15.        custom_encoded = custom_encoded + c
17. 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
