全部问题

再会。我正在尝试（学习）抓取该网站。有数据（有很多这样的带有数据的行，大约28-30个单位）。

    <div class="maxt">
    <temperature-value value="-12" from-unit="c" reactive="">−12</temperature-value>
    </div>

我通过 BeautifulSoup 获取字符串。

maxt = bs.find_all('div', class_= "maxt")

这些线条本身是正确的。

无法从这一行获取值：-12 对于所有内容。

告诉我出了什么问题。

我设法这样做，但也许我可以通过“find...find_all”来做到这一点

temp_list = []
for t in temp:
    temperatyre = t['value']
    if temperatyre != '':
        print(t['value'])
        temp_list.append(temperatyre)

此外，代码可以工作，但选择并不令人满意（它选择了所有温度，但例如只需要 maxt 和 mint）

import requests
from bs4 import BeautifulSoup
 
url = 'https://www.gismeteo.ru/weather-omsk-4578/month/'
headers = {"User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:121.0) Gecko/20100101 Firefox/121.0",}

response = requests.get(url, headers=headers)

bs = BeautifulSoup(response.text, 'lxml')
temp = bs.find_all('temperature-value')

print('всего строк = ' + str(len(temp)))

temp_list = []

for t in temp:
    temperatyre = t['value']
    if temperatyre != '':
        print(t['value'])
        temp_list.append(temperatyre)

我无法弄清楚错误可能出在哪里。

订单.java:

package com.example.demo.model;

import jakarta.persistence.*;

@Entity
@Table(name = "orders")
public class Order {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private long id;

    @Column(name = "customer")
    private String customer;

    @Column(name = "description")
    private String description;

    @Column(name = "price")
    private short price;

    @Column(name = "readiness")
    private boolean readiness;

    public Order() {

    }

    public Order(String customer, String description, short price, boolean readiness) {
        this.customer = customer;
        this.description = description;
        this.price = price;
        this.readiness = readiness;
    }

    public long getId() {
        return id;
    }

    public String getCustomer() {
        return customer;
    }

    public void setCustomer(String customer) {
        this.customer = customer;
    }

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public short getPrice() {
        return price;
    }

    public void setPrice(short price) {
        this.price = price;
    }

    public boolean isReady() {
        return readiness;
    }

    public void setReadiness(boolean isReady) {
        this.readiness = isReady;
    }

    @Override
    public String toString() {
        return "Order [id=" + id + ", customer=" + customer + ", desc=" + description + ", readiness=" + readiness + "]";
    }
}

有一个 DataFrame，您需要在其中比较两列，以便np.nan两np.nan列中的比较产生True.

下面的代码返回两行。
np.nan比较为False.

df = pd.DataFrame({'Город1': ['Москва', 'Ярославль', 'Псков', np.nan,1],
    'Город2': ['Москва', 'Самара', 'Ростов', np.nan,1]})
df[ df['Город1'] == df['Город2'] ]

写这样的比较对我来说不起作用：

df[ (df['Город1'] == df['Город2']) | (df['Город1'].isnull()& df['Город2'].isnull()) ]

我想把比较作为一个条件。

谢谢你！

我们需要一种将英语（用拉丁语书写）名字音译为俄语的方法，同时考虑发音。

我对实用的转录感兴趣，而不仅仅是音译。该链接有一个包含规则的巨大表格，但我什至无法想象如何对它们进行全部编码，并且在许多地方它仍然没有指定在哪种情况下使用哪种音节变体。也许您需要一本大字典。

有一个内置的库transliterate和相应的函数translit("Old White End", "ru")，但它完全没有用，因为它返回Олд Wхите Енд你想看到的东西Олд Уайт Энд。或Дэвис Корт不Давис Цоурт。

有没有现成或半现成的解决方案？
