How do you reverse a right angled triangle in python?
In this shot, we will discuss how to generate an inverted right-angled triangle using numbers in Python. Show
We can print a plethora of patterns using Python. The only prerequisite to do this is a good understanding of how loops work in Python. Here, we will
be using simple DescriptionA triangle is said to be right-angled if it has an angle equal to 90 degrees on its left side. An inverted right-angled triangle is just the inverted form of this with its vertex lying on the bottom. To execute this using Python programming, we will be using two
CodeLet’s look at the below code snippet.
Explanation
CONTRIBUTOR Vinisha Maheshwari Introduction :In this python programming tutorial, we will learn how to print an inverted right-angled triangle programmatically. A right-angled triangle has one 90 degrees angle or right angle. For an inverted right-angled triangle, this right angle will be at the top left corner. The other angles will be 45 degrees each in our example. We will learn how to print the right-angled triangle using numbers or using any other characters. The program will ask the user to enter the height of the triangle if we are printing it using numbers. It will then print each row using numbers. Similarly, if we are printing the triangle using other characters, it will ask the user to enter both height and character to use for the triangle. Let me show you both of these approaches one by one : Python 3 program to print inverted right-angled triangle using number :
You can also download both of these examples from here Output :How does it work?In this example, we are printing an inverted right-angled triangle using only numbers. The numbers are printed serially like 1,2,3,4,5….. If the height is 5: for the first line, we are printing 5 numbers ‘1,2,3,4,5’, for the second line, we are printing 4 numbers ‘1,2,3,4’, for the third line, three numbers ‘1,2,3’ etc.
We can also print the same inverted triangle using any character. Let’s check : Python 3 program to print inverted right-angled triangle using any character :Output :How does it work?This example is the same as the above one. We are running two ‘for’ loops: the outer one will run for the same number of times as the height of the triangle, and the inner one will run based on the current height. Unlike the previous example, we are printing a character to create the triangle. The character is also given by the user. Here, we are using ‘*’ to create the triangle, but we can use ‘$’,’&’,’#’ etc. Conclusion :In this tutorial, we have learned how to print one inverted right-angled triangle in python using numbers or any other characters. This tutorial is a good example of using nested for loops in python. You can modify the program to print one non-inverted right-angle triangle. You can also try to print any other shapes using the same approach. Try to run the example program shown above and drop one comment below if you have any queries. Similar tutorials :
