TASK 3:

m=int(input("你还有三次机会，猜吧："))

    print("2021年5月你的幸运日是",x,"号")

　

 

n=int(input())
m=int(input())
print(f"{n}的{m}进制是:",end="")
x=[]
while(n):
    x.append(n%m)
    n//=m
if m==16:
    i=len(x)-1
    while i>=0:
        if x[i]>9:
            print(chr(x[i]-10+65),end="")
        else:
            print(x[i],end="")
        i-=1
else:
    i=len(x)-1
    while i>=0:
        print(x[i],end="")
        i-=1

 

 

 

 

1，random.randint(1,100）生成的随机整数范围是1-100，包括100。range(1,100)生成的有序序列范围2-99，不包括100.

2，s={random.randint(1,100) for i in range(5)}生成集合，len(s)不一定都是5。
