Hello everyone, welcome back to programminginpython.com! As a part of the series on pattern programming, Here I will explain to you how to print a reverse pyramid pattern or a reverse triangle pattern in Python. In one of my earlier posts, I have explained how to print a pyramid pattern, now I will explain how to print a reverse pyramid pattern in python.

Task

Python Program to print a Reverse Pyramid Pattern or Reverse Triangle Pattern.

Approach

• Read an input integer for asking the range of the triangle using  input()
• Run 3 for loops, one main for row looping, and the other 2 sub-loops for column looping, in the first loop, loop through the range of the triangle for row looping.
• In the second loop, loop through the value of the range from max to 1, this is to print space ` `
• In the third loop, loop through the value of range to max and print *

# Print a Reverse Pyramid

# Range of the Reverse Pyramid
num = int(input("Enter the range: t "))

for rows in range(num, 0, -1):
    for columns in range(0, num-rows):
        print(end=" ")
    for columns in range(0, rows):
        print("*", end=" ")
    print()
