In this shot, we will discuss how to generate an inverted hollow right-angled triangle using stars in Python. We can print a plethora of patterns with Python. The only prerequisite is a good understanding of how loops work in Python. Here, we will use simple
for loops to generate an inverted hollow right-angled triangle with stars.
A 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 the same with its vertex lying on the bottom.
To print an inverted right-angled triangle in Python, we will use 2
Let’s look at the code snippet below.
# Number of rows n = 5 # Loop through rows for i in range(1,n+1): # Loop through columns for j in range(1, n+1): # Printing Pattern if (i==n-j+1) or (j==1) or (i==1): print("*", end=" ") else: print(" ", end=" ") print()
In line 2, we take the input for the number of rows (i.e., the length of the triangle).
In line 5, we create a
for loop to iterate through the number of rows.
In line 8, we create an inner nested
for loop to iterate through the number of columns.
From lines 11 to 14, we use conditional statements to create the pattern. The
end statement helps to stay on the same line.
In line 15, we use the
print() statement to move to the next line.
In this way, we can generate an inverted hollow right-angled triangle using stars in Python.
