Answer to Question #227991 in Python for varun

Question

Number Diamond

Given an integer N as input,

write a program to print a number diamond of 2*N -1 rows as shown below.

Note: There is a space after each number.

In the given example, the number of rows in the diamond is 5

So, the output should be

   1 

   1 2 

 1 2 3 

 1 2 3 4 

1 2 3 4 5 

 1 2 3 4 

 1 2 3 

  1 2

Your code:

N = int(input())

rows = []

for number in range(1, N + 1):

  rows.append(' '.join([str(x) for x in range(1, number + 1)]))

for number in rows[::-1][1::]:

  rows.append(number)

diamond = '\n'.join([x.center(2* N - 1) for x in rows])

print(diamond)

the above code works fine but only 7/10 test cases are passed

for input 15 the output is not the same as expected

Answer 1

row = int(input("Enter the number or rows:  "))


sol = []


for n in range(1, row + 1):


  sol.append(' '.join([str(i) for i in range(1, n + 1)]))


for n in sol[::-1][1::]:


 sol.append(n)


solution = '\n'.join([i.center(2* row - 1) for i in sol])


print(solution)
