In this shot, we will discuss how to generate an inverted equilateral triangle using numbers in Python.
We can print a plethora of patterns using Python. The basic and only prerequisite is a good understanding of how loops work in Python. In this shot, we will use simple
for loops to generate an inverted equilateral triangle using numbers.
A triangle is said to be equilateral if it has the same length on all three sides. An inverted equilateral triangle is the inverted form of the same with its vertex lying on the bottom, pointing downwards.
To execute this using Python programming, we will use two
for loops nested within an outer
Let us look at the code snippet below.
# User Input for number of rows and columns (Length of Triangle) num = 6 # Loop over number of rows and columns for i in range(num, 0, -1): # Spaces across rows for j in range(0, num-i): print(end=" ") # Print spaced stars for j in range(0, i): print(i, end=" ") # Go to next line print()
In line 2, the user gives input to specify the number of rows and columns, i.e., the length of the triangle.
In line 5, we create an outer
for loop to loop over the rows and columns
In lines 8 and 9, we create an inner
for loop to print the initial spaces across the rows.
In line 12, we create another inner loop.
In line 13, we have printed
i which starts with
6 and as it comes down to the rows below, its value gets decremented by .
