In this video we will learn how to make equilateral triangle pattern in python. Learn Python programming for a career development in Programming. In this video we will see : - How to print a Reverse equilateral star triangle pattern using Python. - Understanding the basics of building a pattern. The steps involved are: - First we create a outer loop which controls the number of steps. - Then inside there will be two loops one is for creating spaces and second is for printing stars. - But this time number of spaces will increase and number of stars will decrease in each step. - Also print() is used to move to next line.
