Pyramid in Python

Introduction

Printing a pyramid is a very basic exercise after learning Loop in any programming language.And probably the most challenging one is Pascal Pyramid.

In this blog ,we will be discussing about how we can make one such using just 4 lines of code.

Let’s Begin

Python is a Low-level programming language.It has many easy or rather user-friendly way of handling strings where as in C-Language its not so obvious.So lets come to the topic.

In Python one can add or multiply strings.Like,

"*"*4+"+"

## '****+'

You can also print “Nothing”(!) in Python

"  *"   #---Printing two space followed by a star

## '  *'

Building Pyramid

Let’s look into the pyramid again.

##     *
##    * *
##   * * *
##  * * * *

Now without looking at * ,try to look into the string *,a space followed by star.Bang!!!

• Steps

1. Print n-1 many gaps and *.

2. Print n-2 many gaps and two times * and so on.

So the final code

def pyramid(n):
  for i in range(n,0,-1):
    print(" "*(i-1)+" *"*(n-i))
pyramid(5)
