Program to Print Powers of 2 in Python (Code Examples)

This is your easy tutorial on how to find powers of 2 in Python! In the field of computer science, powers of 2 hold immense significance. They are fundamental in understanding binary representation, bitwise operations, and various algorithms used in programming. 

Python, with its simplicity and versatility, provides a powerful platform for exploring and manipulating powers of 2.

Here, we will guide you through Python programs to calculate powers of 2, perform operations on them, and harness their potential in various scenarios. 

You'll find clear explanations and example code that shows how to generate powers of 2 in Python. We'll explore different approaches, highlighting both basic concepts and advanced techniques, allowing you to deepen your understanding and broaden your programming skills.

Find Powers of 2 in Python Using Anonymous Function

Code

# Power of Two in Python Using Anonymous Function

display_powers_of_2 = lambda n: [print(2**i) for i in range(n+1)]

# Example usage
num = int(input("Enter the number of powers of 2 to display: "))
display_powers_of_2(num)

Output

Enter the number of powers of 2 to display: 12
1
2
4
8
16
32
64
128
256
512
1024
2048

Explanation

  • In this program, we define an anonymous function called display_powers_of_2 using a lambda expression. The function takes a parameter n, which represents the number of powers of 2 in Python to display.

  • Using a list comprehension, we iterate over the range from 0 to n (inclusive) and calculate 2 raised to the power of i. We then print the result using the print function.

  • To test the program, we prompt the user to enter a number using the input function and convert it to an integer using int(). 

We then call the display_powers_of_2 lambda function with the entered number as the argument. The lambda function will iterate over the range and display the powers of 2 up to the specified number.

Print Powers of Two in Python Using for loop

Code

# Display powers of 2 With Python for loop

def display_powers_of_2(n):
    for i in range(n+1):
        print(2**i)

# Example usage
num = int(input("Enter the number of powers of 2 to display: "))
display_powers_of_2(num)

Output

Enter the number of powers of 2 to display: 10

Explanation

  • In this program, we define a function called display_powers_of_2 that takes a parameter n, representing the number of powers of 2 to display.

  • Using a for loop, we iterate over the range from 0 to n (inclusive). For each value of i, we calculate 2 raised to the power of i using the exponentiation operator **. We then print the result using the print function.
