Question

i need this code to print a number of stars depending on how much the user wants and after * it prints no stars. if the user enters a negative number it should print "error invalid number"

this is my code so far:

def stars(n,i):
    
    stars(n, 1)
    if n <= 0:
        return "No stars"

    if i <= n:

        print("* ", end="")

        stars(n, i + 1)

    else:

        print("no stars")

        stars(n - 1, 1)
        
n = int(input("enter an integer"))


def main():
    stars()
    number = n


def stars(n, i):
    if n < 1:
        return

    if i <= n:

        print("* ", end="")

        stars(n, i + 1)

    else:

        
        print("")
        stars(n - 1, 1)


n = int(input("enter an integer: "))
stars(n, 1)

main()

Program

def stars(n):

if n <0:
print( "Error!!! Invalid number.")
return

else:
for i in range(n + 1, 0, -1):
for j in range(0, i - 1):
print("*",end='')
print(end=' ')

print("no stars")

  
def main():
n = int(input("Enter an integer: "))
stars(n)
main()

Output

Enter an integer: 5
***** **** *** ** * no stars
>>>

Enter an integer: 7
******* ****** ***** **** *** ** * no stars
>>>

Enter an integer: -8
Error!!! Invalid number.
