Python  Exercise 5 --- "Astrologer's Stars"

In today’s exercise, what we have to do is, we have to print a pattern similar to that of  a right-angle triangle, such as:

*
**
***
****

You have to follow certain instructions, which are as follows:

• You have to take an integer type variable, and the input of the variable will define the length of the triangle.
• You have to declare another Boolean variable.
• When the value of Boolean is 1 i.e. True, the pattern will be printed as shown above.
• But if the value of Boolean is 0 or false, then the triangle will be printed upside down.

Solution:

a = int(input("Enter the number of lines you want to print \n"))
b = bool(int(input("Enter 0 or 1 \n")))


def star(a, b):
    if b == True:
        c = 1
        while c <= a:
            print(c * "*")
            c = c + 1
    else:
        while a > 0:
            print(a * "*")
            a = a - 1


star(a, b)
