Binary to Decimal in Python

One of the most fundamental concepts in programming is understanding how number systems work. Converting binary numbers to decimal is a common task in many fields, including computer science and data analysis. Python makes it easy to convert binary to decimal with the built-in int() function.

Here's how you can do it:

binary_number = "1011"  # binary representation of the number
decimal_number = int(binary_number, 2)  # Convert binary to decimal
print(f"The decimal value of {binary_number} is {decimal_number}")
        

In this example, the binary number "1011" is converted to its decimal equivalent, 11. This is just one of the many handy features Python provides for performing quick mathematical tasks.

Boa vs Python

When comparing Boa and Python, we’re likely referring to different approaches or technologies in programming. Boa constrictor is a large snake, while Python is a programming language. If you’re interested in comparing Python to other programming languages, such as C++ or Java, Python’s clear syntax and versatility often make it a preferred choice for many developers.

Python is known for its readability, ease of learning, and extensive library support, which gives it a significant edge in the world of programming.

Call by Value and Call by Reference in Python

In Python, understanding how function arguments are passed is crucial. While many languages use call by value or call by reference, Python uses a unique mechanism called "call by object reference" or "call by assignment".

• Call by Value: The actual value of the variable is passed to the function. Changes made inside the function do not affect the original variable.
• Call by Reference: A reference to the actual memory location of the variable is passed. Changes made inside the function will affect the original variable.

However, Python always passes references to objects, not the actual value. Whether the object is mutable or immutable affects whether changes are reflected outside the function. Let’s see an example:

def modify_list(my_list):
    my_list.append(4)  # This will modify the original list

original_list = [1, 2, 3]
modify_list(original_list)
print(f"Modified list: {original_list}")  # Output: [1, 2, 3, 4]
        

In this case, since lists are mutable in Python, the original list is modified.

Code with Harry Python
