Python中def()函数的实战练习题

def zhishu(num):
    for i in range(2,num//2+1):
        if num%i==0:
            return (f"{num}不是质数")
    return (f"{num}是质数")
print(zhishu(5))

def zhishu(num):
        for i in range(2,num//2+1):
            if num%i==0:
                return  False
        return True
for i in range(50,151):
    if zhishu(i):
        print(f"{i}是质数")

def num1():
 for num in range(100,1000):
    i = num // 100 
    j = num // 10 % 10
    k = num % 10 
    if num == i ** 3 + j ** 3 + k ** 3:
        print ("输出的水仙花数为：%s"%(num))
num1()

在这里插入代码片num = int (input("请输入大于9的数字："))
if num<100:
    i=num%10
    j=num//10
    sums=i+j
    print(sums)
    if (num-sums)%9==0:
        print("该数能够被9整除,验证成功")
    else:
        print("该数能够被9整除，验证失败")
elif num>=100 and num<=1000:
        i=(num %100)%10
        j= (num %100)//10
        k=num//100
        sums=i+j+k
        print(sums)
        if (num -sums)/9==0:
            print("该数能够被9整除，验证成功")
        else:
            print('这个数不能被9整除，验证失败')

def num():
    for i in range(10000,100000):
       num1=i * 10 + 7
       num2=i + 700000
       if num2==5*num1:
           print(i)
num()

def nums():
    for i in range(1,20):
        for j in range(i,141):
              if i*j==140:
                  print("%d/%d"%(i,j))
nums()

def nums():
    for num in range(1,100000):
        n=num/80
        if n%7==0 and n%2==1 and n%3==1 and n%4==1 and n%5==1 and n%6==1:
            print('这个自然数为：%s'%(n))
nums()

def nums():
    for num in range(100,1000):
        i=(num %100)%10
        j= (num %100)//10
        k=num//100
        sums = i+j+k
        if sums==num/11:
            print("满足条件的三位数为：%s"%num)
            break
nums()

方法一
coin=[10, 8, 5, 3, 27, 99]
x=0
for i in coin:
	if i%2==0:
		x+=i//2
	else:

# 方法二,递归法

    return coin(n-1)+coin(n-2)
print("最少%s"%(coin(10))+"次可以拿完硬币")
