用Python爬取自主品牌汽车，看看国产汽车究竟长什么样？(上)

有态度地学习

就在上周，公司的XX总过来和我说，小伙子要好好工作，多学点东西，不要就想着hun，工作的时候多动动脑子，提高工作效率，我的内心...

好吧，那就写点东西。刚好公司是做AI交通的，需要汽车标签分类。与我这个前主机厂工程师相比，公司里的人或许对汽车分类并不是很清楚。冥冥之中，自有天意，还是与汽车息息相关。那么作为一名前主机厂工程师和FSCer，就有必要来科普一波。这里来一波学弟学妹们今年的成果，小八帅照一张。恭喜他们在今年取得全国第14名的好成绩。

就如昨日IG夺冠一般，LPL终于有了一个属于自己的S赛冠军，LOL最高的荣誉。车队也是在今年，建队的第八个年头，获得了一个不错的成绩，可谓八年磨一剑。翻过这座山，他们就会听到你们的故事，加油！！！

说到汽车，很多人对国外品牌比起国内品牌，会有更多的了解，谁叫国产汽车不争气。当然现在的自主品牌也在不断缩小与国外品牌的差距，新能源也算是一个突破口，弯道超车不是梦。

所以本次收集的数据，都是自主品牌汽车，外资合资通通不要。首先去中国政府网来看看今年上半年自主品牌汽车的销量，这里面不单单包含乘用车。所以你会发现，新能源汽车老大—比亚迪，客车老大—宇通，商用车老大—北汽福田，以及皮尺部—众泰并不在榜上。前任东家也在榜上，倍感欣慰，熟悉我的朋友应该知道...

新能源汽车与燃油车无非就是动力方面有区别，车型没什么区别，所以就以爬取燃油车为例。这里插一句，其实车企研发一辆新款车型不容易的，一般需要耗资上亿，在研发的时候就会考虑燃油，混动，纯电动三种类型的。现在所谓的电动车，好多都是是车企的热销车型改变动力形式而已(因为电动车不好卖，不能专门去研发一波吧，亏本的生意~)。接下来就一个个来说啦！！！

1. 上汽

上汽的自主品牌有荣威，名爵，大通，五菱，宝骏。上汽算是很多汽车人的奋斗目标，优越的地理位置，相对不错的薪水。不过比起互联网，还是捉襟见肘。

比如来看看下面这些数据。2017年上汽的全年营收是 8579.78 亿，净利润 344.1 亿。2017年腾讯的全年营收是 2377.6 亿元，净利润 715 亿元。上汽利润率 4% ，腾讯利润率 30% ，只能说都是行业巨头，差距咋这么大呢？

2. 长安

长安作为自主品牌的老大哥，现如今的奇瑞已经濒临出售的局面，这个老大哥又该何去何从呢？

3. 吉利汽车

吉利自从收购了沃尔沃后，便飞速发展，成为世界500强。一方面，是从沃尔沃学到了很多东西，设计、制造、采购、营销等。另一方面，也是离不开政策的支持，比如你看看它现在可是戴姆勒的第一大股东，吉利哪里来那么多钱，显而易见~

response = requests.get(url=url, headers=headers)
res = response.text
html = etree.HTML(response.text)
result = html.xpath('//div[@class="car"]/img/@src')
Car_Type = ['Car', 'SUV']
for i in range(2):
    folder_path = "F:/Car/GEELY_AUTO/"   Car_Type[i]   "/"
    os.makedirs(folder_path)
for j in range(17):
    url = result[j]
    r = requests.get(url)
    picture_name = url.replace('https://dm30webimages.geely.com/GeelyOfficial/Files/Car/CarType/', '')
    if 0 < j < 4 or 6 < j < 12 or j == 16:
        with open('F:\Car\GEELY_AUTO\Car\'   picture_name, 'wb') as f:
            f.write(r.content)
    elif 3 < j < 7 or 11 < j < 16:
        with open('F:\Car\GEELY_AUTO\SUV\'   picture_name, 'wb') as f:
            f.write(r.content)
    else:
        continue
    f.close()
    print(url)

未完待续，还有七个品牌，待我喝口水先~
