有时我们需要一次安装多个第三方库，单个操作比较繁琐，可通过此脚本安装想要的库。

**注意：需要安装第三方库的名称请保存在文件LibName.csv中。**

可分组进行安装，LibName.csv文件中每行代表一组。

完整代码如下：

def main():
        path = 'LibName.csv'
        printInform()
        items = getItems(path)
        dic = InstallLibs(items)
        printSummary(dic)
    
    def printInform():
        s = ''' 欢迎使用Python第三方库批量安装脚本 需要安装第三方库的名称请保存在文件LibName.csv中 回车开始安装'''
        print(s)
        input()
       
    
    def getItems(path):
        fo = open(path)
        ls = []
        print('')
        for line in fo:
            print(line)
            line = line.replace('\n','')
            ls.append(line.split(','))
        fo.close()
        print('')
        return ls
    
    def InstallLibs(items):
        import time
        num = 0
        lts = []; lfs = [];
        dic = { }
        for row in items:
            print("开始安装。。。。。。\n")
            for column in row:
                start = time.perf_counter()
                for i in range(3):
                    print("\n")
                if InstallLib(column):
                    lts.append(column)
                    lstatus = '成功'
                else:
                    lfs.append(column) 
                    lstatus = '失败'
                print("{}安装完成。。。\n".format(column))
                end = time.perf_counter()
                ltime = end - start
                dic[column] = [ltime,lstatus]
            print("{}安装成功".format(','.join(lts)))
            if lfs != []:
                print("{}安装失败".format(','.join(lfs)))
            num = num+1
            print('第{}组安装完成\n'.format(num))
            print("回车继续安装下一组")
            input()
            lts = []; lfs = []
        return dic
    
    def InstallLib(item):
        from os import system
        try:
            system("pip install " + item)
            return True
        except:
            return False
       
    def printSummary(dic):
        print("所有库均已安装完成，以下为安装详细信息：")
        s = "\t{:<25}{:>7}s{:^15}".format("Name","Time"," Status")
        lt = "\t{:<25}{:>7.2f}s{:^15}"
        print(s)
        for key in dic.keys():
            print(lt.format(key,dic[key][0],dic[key][1]))
            s += '\n' + lt.format(key,dic[key][0],dic[key][1])
        for i in range(5):
            print("\t\t.\t\t.")
        try:
            saveFile(s)
        except:
            print("日志文件保存失败")
        input("\n按回车退出程序 . . . \n")
    
    def saveFile(s):
        import time
        import os
        root = ".//日志//"
        path = root + "PythonLibInstall" + time.strftime("%Y%m%d_%H%M%S.log")
        if not os.path.exists(root):
            os.mkdir(root)
        with open(path,'w') as f:
            f.write(s)
            f.close()
            print("日志文件保存成功")
    
    main()
