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.
