Diamond pattern in python using while loop
Feb 28, 2021
n = int(input("Enter n:"))
m = (n+1)/2
i = 1
while i<=n:
if i<m:
b = m-i
s = 2*i-1
else:
b = i - m
s = 2*(n-i) + 1
j = 1
while j<=b:
print(" ",end="")
j += 1
j = 1
while j<=s:
print("*",end="")
j +=1
print()
i += 1Output:
n = 11 *

logic :
For upper triangle : blank space = m - i
star : 2*i - 1
For lower triangle: blank space: i -m
star : 2*(n-i) -1
