Python Program to Print Star-Hyphen Combination Pattern - 1 (Alternating Symbols)
A Python Program to Print Star-Hyphen Combination Pattern - 1 (Alternating Symbols)?
Code Explanation:
● n = 5 defines half the height of the pattern (middle row length is * * * * *).
● First loop prints the upper half (1 to 5).
● Second loop prints the lower half (4 to 1).
● spaces = n - i aligns everything to the right side.
● char toggles between * (odd rows) and - (even rows).
● " " * spaces gives proper alignment to the right.
● (char + " ") * i prints the symbols with a space between them.
Program:
n = 5
# Upper half
for i in range(1, n + 1):
symbol_count = 2 * i - 1
spaces = n - i
char = '*' if i % 2 != 0 else '-'
print(" " * spaces + (char + " ") * i)
# Lower half
for i in range(n - 1, 0, -1):
symbol_count = 2 * i - 1
spaces = n - i
char = '*' if i % 2 != 0 else '-'
print(" " * spaces + (char + " ") * i)
