Python Program to Print Series 1, 22, 333, 4444…n

by

In the previous article, we have discussed Python Program to Print Series 6, 11, 21, 36, 56…n
Given a number N and the task is to print the series (1,22,333,4444…N) for the given number N in Python.

Examples:

Example1:

Input:

Given Number = 5

Output:

The above series till the given number{ 5 } is :
 1 22 333 4444 55555

Example2:

Input:

Given Number = 8

Output:

The above series till the given number{ 8 } is :
 1 22 333 4444 55555 666666 7777777 88888888

Program to Print Series 1,22,333,4444…n in Python

Below are the ways to print the series (1,22,333,4444…N) for the given number N in Python.

Method #1: Using For Loop (Static Input)

Approach:

  • Give the number N as static input and store it in a variable.
  • Loop till the given number using the for loop.
  • Inside the For loop, Iterate till the above iterator value of the parent for loop using another Nested For loop(Inner For loop).
  • Print the iterator value of the parent for loop separated by spaces.
  • Print the space by using the end keyword.
  • The Exit of the Program.

Below is the implementation:

# Give the number N as static input and store it in a variable.
gvn_numb = 5
print("The above series till the given number{", gvn_numb, "} is :")
# Loop till the given number using the for loop.
for itr in range(gvn_numb+1):
  # Inside the For loop, Iterate till the above iterator value of the parent for loop
  # using another Nested For loop(Inner For loop).
    for m in range(itr):
      # Print the iterator value of the parent for loop separated by spaces.
        print(itr, end="")
    # Print the space by using the end keyword.
    print(end=" ")

Output:

The above series till the given number{ 5 } is :
 1 22 333 4444 55555

Method #2: Using For loop (User Input)

Approach:

  • Give the number N as user input using the int(input()) function and store it in a variable.
  • Loop till the given number using the for loop.
  • Inside the For loop, Iterate till the above iterator value of the parent for loop using another Nested For loop(Inner For loop).
  • Print the iterator value of the parent for loop separated by spaces.
  • Print the space by using the end keyword.
  • 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 = "))
print("The above series till the given number{", gvn_numb, "} is :")
# Loop till the given number using the for loop.
for itr in range(gvn_numb+1):
  # Inside the For loop, Iterate till the above iterator value of the parent for loop
  # using another Nested For loop(Inner For loop).
    for m in range(itr):
      # Print the iterator value of the parent for loop separated by spaces.
        print(itr, end="")
    # Print the space by using the end keyword.
    print(end=" ")

Output:

Enter some Random Number = 8
The above series till the given number{ 8 } is :
1 22 333 4444 55555 666666 7777777 88888888
