9 9 9 =6

要求是填上符号，等式成立。好吧，我又偷懒了。

for i in map(str,range(1,11)):
    for j in range(10000):
        c=random.choice(["+","-","*","/","**0.5",""])
        b=random.choice(["+","-","*","/","**0.5",""])
        e=random.choice(["**0.5",""])
        if c=="**0.5":
            c=c+random.choice(["+","-","*","/"])
        if b=="**0.5":
            b=b+random.choice(["+","-","*","/"])
        if eval(i+c+i+b+i+e)==6:
            print i+c+i+b+i
            break
