Python Program to Print 1-101-10101 Binary Number Pyramid Pattern

Question: write a program in Python to generate a 1-101-10101 binary number pyramid pattern up to n lines, where n is given by the user.

Python Source Code: 1-101-10101 Pattern

# Program to print 1-101-10101

n = int(input("Enter number of lines of pattern: "))

for i in range(1,n+1):
    for j in range(1, n-i+1):
        print(" ", end="")
        
    for k in range(1,2*i):
        print(k%2, end="")
        
    print()

The output of the above program is:

Enter number of lines of pattern: 12
           1
          101
         10101
        1010101
