This Python code generates Floyd’s Triangle based on user input. Floyd’s Triangle is a right-angled triangular array of natural numbers.
n = int(input("Enter number of rows of floyd`s trangle: "))
k = 1
for i in range(1, n + 1):
for j in range(1, i + 1):
print(k, end=" ")
k = k + 1
print()
Enter number of rows of floyd`s trangle: 10

n = int(input("Enter number of rows of Floyd's triangle: "))
n
.k = 1
k
is initialized to 1. This variable keeps track of the current number to be printed in the triangle.for i in range(1, n + 1):
for j in range(1, i + 1):
print(k, end=" ")
k = k + 1
print()
for i in range(1, n + 1)
n
inclusive. Each iteration represents a row in Floyd’s Triangle.for j in range(1, i + 1):
print(k, end=" ")
k = k + 1
for j in range(1, i + 1)
i
inclusive, determining the number of elements in the current row.print(k, end=" ")
k
followed by a space. The end=" "
parameter ensures that the numbers are printed on the same line separated by spaces.k
:k = k + 1
k
, k
is incremented by 1 to prepare for the next number to be printed.print()
print()
is called to move to the next line. This ensures that each row of Floyd’s Triangle starts on a new line.If the user inputs 5
for n
, the output will be:
1
2 3
4 5 6
7 8 9 10
11 12 13 14 15
