Alphabet Pattern 'B' in Python

In this Blog I am printing pattern B using Python

Code:

str="";
for Row in range(0,7):
    for Col in range(0,7):
        if (Col == 1 or ((Row == 0 or Row == 3 or Row == 6) and (Col < 5 and Col > 1)) or (Col == 5 and (Row != 0 and Row != 3 and Row != 6))) :
            str=str+"*"
        else:
            str=str+" "
    str=str+"\n"
print(str);

Output:
