Print downward Half-Pyramid Pattern with Star (asterisk)

Here’s an example Python code to print a downward half-pyramid pattern with stars:

# Set the number of rows
num_rows = 5

# Loop through each row from num_rows to 1
for i in range(num_rows, 0, -1):
    # Loop through each column from 1 to i
    for j in range(1, i+1):
        # Print a star and a space, separated by nothing
        print("* ", end="")
    # Print a newline character to move to the next row
    print()

In this code, we use a nested loop to print the downward half-pyramid pattern. The outer loop iterates over each row from the specified number of rows down to 1, using the range() function with a step value of -1. The inner loop iterates over each column from 1 to the current row number, using the range() function with the i+1 argument. For each column, we print a star and a space, separated by nothing, using the end parameter of the print() function. Finally, we use another print() statement without any arguments to add a newline character and move to the next row.

When you run this code, it should output the downward half-pyramid pattern with stars:

* * * * * 
* * * * 
* * * 
* * 
* 

Note that you can change the value of num_rows to print the pattern with a different number of rows.
