def full_pyramid(n):
for i in range(1, n + 1):
# Print leading spaces
for j in range(n - i):
print(" ", end="")
# Print asterisks for the current row
for k in range(1, 2*i):

def full_pyramid(n):
for i in range(1, n + 1):
# Print leading spaces
print(" " * (n - i), end="")
# Print asterisks for the current row
print("*" * (2*i-1))

Tip

Just for educational purposes, here's an oneliner version:

(lambda n : print('\n'.join([ f'{" " * (n-i)}{"*" * (2*i-1)}' for i in range(1, n+1) ])))(int(input('Size of triangle: ')))
