Python: Create a coded string from a given string, using specified formula

Python Basic - 1: Exercise-121 with Solution

String Encoding with Rules

Write a Python program to create a coded string from a given string, using a specified formula.

Replace all 'P' with '9', 'T' with '0', 'S' with '1', 'H' with '6' and 'A' with '8'

Sample Solution-1:

Python Code:

# Define a function 'test' that translates characters in the input string based on a mapping.
def test(input_str):
    # Use the 'translate' method along with 'str.maketrans' to create a mapping and perform translation.
    translated_str = input_str.translate(str.maketrans('PTSHA', '90168'))
    return translated_str

# Test the 'test' function with different input strings.
str1 = "PHP"
print("Original string: ", str1)
print("Coded string: ", test(str1))

str2 = "JAVASCRIPT"
print("\nOriginal string: ", str2)
print("Coded string: ", test(str2))

Sample Output:

Original string:  PHP
Coded string:  969

Original string:  JAVASCRIPT
Coded string:  J8V81CRI90

Explanation:

Here is a breakdown of the above Python code:

• Translation function (test function):
• The "test()" function is defined to perform character translation in an input string.
• It uses the str.translate method along with str.maketrans to create a mapping and perform the translation.

Sample Solution-2:

Python Code:

# Define a function 'test' that replaces specific characters in the input string with predefined values.
def test(input_str):
    # Use the 'replace' method to replace each specified character with its corresponding value.
    translated_str = input_str.replace('P', '9').replace('T', '0').replace('S', '1').replace('H', '6').replace('A', '8')
    return translated_str

# Test the 'test' function with different input strings.
str1 = "PHP"
print("Original string: ", str1)
print("Coded string: ", test(str1))

str2 = "JAVASCRIPT"
print("\nOriginal string: ", str2)
print("Coded string: ", test(str2))

Sample Output:

Original string:  PHP
Coded string:  969

Original string:  JAVASCRIPT
Coded string:  J8V81CRI90

Explanation:

Here is a breakdown of the above Python code:

• Translation Function (test function):
• The "test()" function is defined to replace specific characters in an input string with predefined values.
• It uses the "replace" method to replace each occurrence of the specified characters with their corresponding values.
