Python Coding challenge - Day 229 | What is the output of the following Python Code?

 

Code:

print('%x, %X' % (15, 15))

Solution and Explanation:

The code print('%x, %X' % (15, 15)) in Python uses string formatting to convert the integer 15 into hexadecimal format. Here is a step-by-step explanation:

1. String Formatting:

   • The % operator is used for formatting strings in Python. It allows you to embed values inside a string with specific formatting.

2. Format Specifiers:

   • %x and %X are format specifiers used for converting integers to their hexadecimal representation.
     • %x converts the integer to a lowercase hexadecimal string.
     • %X converts the integer to an uppercase hexadecimal string.

3. Tuple of Values:

   • The (15, 15) part is a tuple containing the values to be formatted. Each value in the tuple corresponds to a format specifier in the string.

4. Putting It All Together:

   • %x will take the first value from the tuple (15) and convert it to a lowercase hexadecimal string, which is f.
   • %X will take the second value from the tuple (also 15) and convert it to an uppercase hexadecimal string, which is F.

The resulting string will be "f, F", which is then printed to the console.

Here’s the breakdown of the code:

• %x -> f
• %X -> F

When you run the code print('%x, %X' % (15, 15)), it outputs: f, F
