Day 38: Python Program to Print Inverted Star Pattern

 

rows = int(input("Enter the number of rows: "))

for i in range(rows, 0, -1):

    print("*" * i)

#source code --> clcoding.com

Code Explanation:

1. Input: Number of Rows

rows = int(input("Enter the number of rows: "))

input(): Prompts the user to enter a value.

int(): Converts the input (string) into an integer.

rows: Represents the total number of rows in the reverse triangle.

Example:

If the user inputs 5, then:

rows = 5

2. Reverse Triangle Logic

for i in range(rows, 0, -1):

range(rows, 0, -1):

Starts at rows (e.g., 5).

Stops at 0 (not inclusive).

Decrements by -1 in each iteration, creating a countdown.

i: Represents the current row number. The value of i starts from rows and decreases to 1.

Example:

For rows = 5, the range(rows, 0, -1) produces:

5, 4, 3, 2, 1

3. Print Asterisk Pattern

print("*" * i)

"*" * i:

Repeats the asterisk (*) i times for the current row.

For example, if i = 5, "*" is repeated 5 times (*****).

print():

Outputs the repeated asterisks on a new line, creating one row of the triangle.
