I am trying to run j loop for n-i time but in for loop on trying same i am getting invalid syntax error

Question

I wanted to print * pattern, so I was trying to run the j loop that is representing column has to run (n-i) times to print that many stars on ith row.

def pattern2(n):
    for i in range(0,n):
        for j in range(0, (n-i)):
            print("*", end=" ")
        print("\r")
n=int(input("enter no of rows: "))
pattern2(n)

SyntaxError: invalid syntax (<string>, line 3)
