Python Program to Print Series 1, 2, 4, 8, 16, 32…n

In the previous article, we have discussed Python Program to Swap Upper Diagonal Elements with Lower Diagonal Elements of Matrix.
Given a number N and the task is to print the series (1,2,4,8,16,32…N) till the given number N in Python. You will get what is the 1, 2, 4, 8, 16, 32 series in python, Print 1 2 4 8 16 In Python, Geometric Sequence Program In Java 1 2, 4, 8, 16, Program To Display Geometric Sequence In Java, Implement A Program To Display The Geometric Sequence In Java, Program That Print 1 2 4 8 16 32 64 128 Java, 1 2 4 8 16 Series In Java, N In Python, 1 2 4 7 11 Series In Python, Print 1 2 4 8 16 In Python Using For Loop, Series Program In Python, Geometric Progression Program In Java, Print Series In Python etc.. in this article.

Examples:

Example1:

Input:

Given Number = 200

Output:

The above series till the given number{ 200 } is : 
1 2 4 8 16 32 64 128

Explanation:

1, 1*2, 2*2, 4*2, 8*2, 16*2, 32*2, 64*2
we cannot have 128*2=256 because it exceeds the given limit number 200.

Example2:

Input:

Given Number = 50

Output:

The above series till the given number{ 50 } is :
1 2 4 8 16 32

Explanation:

1, 1*2, 2*2, 4*2, 8*2, 16*2
we cannot have 32*2= 64 because it exceeds the given limit number 50.

Program to Print Series 1,2,8,16,32…n in Python

Below are the ways to print the series (1,2,8,16,32…N) till the given number N in Python:

Method #1: Using While Loop (Static Input)

Approach:

  • Give the number N as static input and store it in a variable.
  • Take a variable to say itr and initialize its value to 1.
  • Loop until the above-declared variable itr value is less than or equal to the given number using the while loop.
  • If it is true then print the value of itr separated by spaces.
  • Multiply the itr value with 2 and store it in the same variable itr.
  • The Exit of the Program.

Below is the implementation:

# Give the number N as static input and store it in a variable.
gvn_numb = 200
# Take a variable to say itr and initialize its value to 1.
itr = 1
# Loop until the above-declared variable itr value is less than or equal to the
# given number using the while loop.
print("The above series till the given number{", gvn_numb, "} is :")
while itr <= gvn_numb:
  # If it is true then print the value of itr separated by spaces.
    print(itr, end=" ")
    # Multiply the itr value with 2 and store it in the same variable itr.
    itr *= 2

Output:

The above series till the given number{ 200 } is :
1 2 4 8 16 32 64 128

Method #2: Using While loop (User Input)

Approach:

  • Give the number N as user input using the int(input()) function and store it in a variable.
  • Take a variable to say itr and initialize its value to 1.
  • Loop until the above-declared variable itr value is less than or equal to the given number using the while loop.
  • If it is true then print the value of itr separated by spaces.
  • Multiply the itr value with 2 and store it in the same variable itr.
  • The Exit of the Program.

Below is the implementation:

# Give the number N as user input using the int(input()) function and store it in a variable.
gvn_numb = int(input("Enter some Random Number = "))
# Take a variable to say itr and initialize its value to 1.
itr = 1
# Loop until the above-declared variable itr value is less than or equal to the
# given number using the while loop.
print("The above series till the given number{", gvn_numb, "} is :")
while itr <= gvn_numb:
  # If it is true then print the value of itr separated by spaces.
    print(itr, end=" ")
    # Multiply the itr value with 2 and store it in the same variable itr.
    itr *= 2

Output:

Enter some Random Number = 50
The above series till the given number{ 50 } is :
1 2 4 8 16 32
