Python Program to Print Inverted Triangle Using Star-Hyphen
A Python Program to Print Inverted Triangle Using Star-Hyphen?
Code Explanation:
● Function Definition:
A function reverse_star_hyphen_tree(levels) is created to print an upside-down tree using stars (*) and hyphens (-).
● Reverse Loop:
The for loop runs in reverse from levels - 1 down to 0 to create the inverted pattern.
● Space Calculation:
spaces = levels - i - 1 calculates the leading spaces to center-align the pattern.
● First Line (Bottom of Tree):
When i == 0, it prints only a single *, forming the tip of the tree.
● Other Lines:
For other values of i, it prints a line starting and ending with * and filled with - in between.
The number of hyphens is calculated as (2 * i - 1).
● Final Pattern:
The result is a reverse triangle with alternating size, starting from wide base (*-----*) to a single * at the bottom
Program:
def reverse_star_hyphen_tree(levels):
for i in range(levels - 1, -1, -1):
spaces = levels - i - 1
if i == 0:
print(' ' * spaces + '*')
else:
hyphens = '-' * (2 * i - 1)
print(' ' * spaces + '*' + hyphens + '*')
reverse_star_hyphen_tree(5)
