i applied this code in pascal triangle it is compiling successfully but not sumbiting this answer

#3

Can someone please check this code for pascal triangle. I was getting correct output , but not able to submit code. It’s saying ‘wrong answer’

n=int(input())
h=((n-1)*2)+1
l=[]
for i in range(n):
l.append([’ ']*h)
p=2
l[0][n-1]=1
for i in range(1,n,1):
j=(n-1)-i
l[i][j]=1
l[i][j+p]=1
p=p+2
j=j+2
while l[i][j]!=1:
l[i][j]=l[i-1][j-1]+l[i-1][j+1]
j=j+2

for i in l:
for j in i:
print(j,sep=’ ‘,end=’’)
print()
