Python 练习实例4（Python 100例）

题目：输入某年某月某日，判断这一天是这一年的第几天？

程序分析：以3月5日为例，应该先把前两个月的加起来，然后再加上5天即本年的第几天，特殊情况，闰年且输入月份大于2时需考虑多加一天：

程序代码：

i = int(raw_input('yuar:'))

j = int(raw_input('month:'))

k = int(raw_input('day:'))

arr = [31,28,31,30,31,30,31,31,30,31,30,31]

r = 0

for idx in range(0,13):

    if j-1>idx:

        r+=(arr[idx])

if (j>2)and((i%4==0)and(i%100!=0)or(i%400==0)):

                r=r+1

print r+k

Python 练习实例5（Python 100例）

题目：输入三个整数x,y,z，请把这三个数由小到大输出。

程序分析：我们想办法把最小的数放到x上，先将x与y进行比较，如果x>y则将x与y的值进行交换，然后再用x与z进行比较，如果x>z则将x与z的值进行交换，这样能使x最小。

程序代码：

方法一：

x=int(raw_input('x:'))

y=int(raw_input('y:'))

z=int(raw_input('z:'))

if y>x:

    min=x

    max=y

elif y

    min=y

    y=x

    y=min

if z>y:

    print (x,y,z)

elif z

    print (z,x,y)

else:

    print (x,z,y)

方法二：

l = []

for i in range(3):

    x = int(raw_input('integer:\n'))

    l.append(x)

l.sort()

print l

【程序32】题目：Press any key to change color, do you want to try it. Please hurry up!   （c语言经典编程实例100题）

程序代码：

方法一：

#include

#include

#include

int textbackground(short iColor)

{

    HANDLE hd = GetStdHandle(STD_OUTPUT_HANDLE);

    CONSOLE_SCREEN_BUFFER_INFO csbInfo;

    GetConsoleScreenBufferInfo(hd, &csbInfo);

    return SetConsoleTextAttribute(hd, (iColor<<4)|(csbInfo.wAttributes&~0xF0));

}

void main(void)

{

    int color;

    for(color=0;color<16;color++)

    {

        textbackground(color);//设置文本的背景颜色

        cprintf("this is color%d\r\n",color);

        cprintf("press any key to continue\r\n");

        getch();//输入的字符看不见

    }

}

方法二：

#include

#include

#include

#include

int main()

{ 

        printf("This is color %d\r\n", 0);

         printf("Press any key to continue\r\n");

        system("color 1f");

        system ("pause");

        system("cls");

        getch();

        printf("This is color %d\r\n", 1);

        printf("Press any key to continue\r\n");

        system("color 2f");

        system ("pause");

        system("cls");

        getch();

        printf("This is color %d\r\n", 2);

        printf("Press any key to continue\r\n");

        system("color 3f");

        system ("pause");

        system("cls");

        getch();

        printf("This is color %d\r\n", 3);

        printf("Press any key to continue\r\n");

        system("color 4f");

        system ("pause");

        system("cls");

        getch();

        printf("This is color %d\r\n", 4);

        printf("Press any key to continue\r\n");

        system("color 5f");

        system ("pause");

        system("cls");

        getch();

        printf("This is color %d\r\n", 5);

        printf("Press any key to continue\r\n");

        system("color 6f");

        system ("pause");

        system("cls");

        getch();

        printf("This is color %d\r\n", 6);

        system("color 7f");

        system ("pause");

        system("cls");

        getch();

        printf("This is color %d\r\n", 7);

        printf("Press any key to continue\r\n");

        system("color 8f");

        system ("pause");

        system("cls");

        getch();

        printf("This is color %d\r\n", 8);

        printf("Press any key to continue\r\n");

        system("color 9f");

        system ("pause");

        system("cls");

        return 0;

}
