Step by Step solution about How to resolve the algorithm Case-sensitivity of identifiers step by step in the Python programming language

The provided Python code demonstrates the use of variables and string formatting. Here's a step-by-step explanation of what the code does:

1. Variable Assignment: The code assigns three different values to three different variables named dog, Dog, and DOG:

   • dog is assigned the string "Benjamin".
   • Dog is assigned the string "Samba".
   • DOG is assigned the string "Bernie".

2. String Formatting: The code uses an f-string (formatted string literal) to print a message to the console. F-strings allow you to embed expressions inside string literals using curly braces {}.

3. Printing the Message: The print() function is used to output a message to the console. The message is constructed using the f-string:

   • f"The three dogs are named {dog}, {Dog} and {DOG}.": This f-string evaluates the expressions inside the curly braces and inserts their values into the string.
   • {dog}: This expression evaluates to the value of the dog variable, which is "Benjamin".
   • {Dog}: This expression evaluates to the value of the Dog variable, which is "Samba".
   • {DOG}: This expression evaluates to the value of the DOG variable, which is "Bernie".

4. Output: When the code is executed, the following message will be printed to the console:

   • The three dogs are named Benjamin, Samba and Bernie.

In summary, the code assigns three different dog names to three variables and then uses an f-string to print a message that lists the names of all three dogs.

dog = 'Benjamin'
Dog = 'Samba'
DOG = 'Bernie'

print(f"The three dogs are named {dog}, {Dog} and {DOG}.")
