Pattern in Python

 

a = int(input("How many row u want "))

b = 1

c = input("Enter 1 for true and 2 for false ")

#  Through while loop

# if c == "1":

#     while b<=a:

#         print(b*"*")

#         b =b+16

# if c == "2":  

#     while a>0:

#         print(a*"*")

#         a = a-1

# Through for loop

if c == "1":

    for i in range(a+1):

        print("*"*(i))

if c == "2":

   for i in reversed(range(a+1)):

       print("*"*(i))
