Alphabet Pattern 'Y' in Python

In this Blog I am printing pattern 'Y' using Python.

Code:

str="";
for Row in range(0,7):
    for Col in range(0,7):
        if (((Col == 1 or Col == 5) and Row < 2) or Row == Col and Col > 0 and Col < 4 or (Col == 4 and Row == 2) or ((Col == 3) and Row > 3)):
            str=str+"*"
        else:
            str=str+" "
    str=str+"\n"
print(str);

Output:
