Left Half Diamond Pattern in Python
A Left Half Diamond Pattern in Python
Short Description:
This Python program prints a left-aligned half diamond using asterisks (*).
It first prints an increasing triangle with spaces to the left, then a decreasing triangle, forming a diamond shape aligned to the left.
Explanation (in dot points):
- rows = int(input(...))
• Takes the number of rows as input from the user.
- for i in range(1, rows + 1)
• Creates the upper half of the diamond.
• Spaces decrease while stars increase.
- for i in range(rows - 1, 0, -1)
• Creates the lower half of the diamond.
• Spaces increase while stars decrease.
- " " * (rows - i)
• Adds spaces before stars to align the pattern to the left.
- "*" * i
• Prints i stars in each row.
Program:
rows = int(input("Enter the number of rows: "))
for i in range(1, rows + 1):
print(" " * (rows - i) + "*" * i)
for i in range(rows - 1, 0, -1):
print(" " * (rows - i) + "*" * i)
