使用Python在车站之间获取火车

假设您想使用印度铁路旅行，并想寻找指定车站之间的火车。手动执行此操作可能会非常忙碌。因此，在本文中，我们将编写一个脚本，该脚本将自动从 railyatri 获取数据，并在指定车站之间告诉列车名称及其代码。

需要的模块

• bs4 : Beautiful Soup(bs4) 是一个Python库，用于从 HTML 和 XML 文件中提取数据。这个模块没有内置于Python中。要安装此类型，请在终端中输入以下命令。

pip install bs4

• requests ： Request 允许您非常轻松地发送 HTTP/1.1 请求。这个模块也没有内置于Python中。要安装此类型，请在终端中输入以下命令。

pip install requests

让我们看看脚本的逐步执行。

第一步：导入所有依赖

Python3

# import module
import requests
from bs4 import BeautifulSoup

第 2 步：创建 URL 获取函数

# user define function 
# Scrape the data 
def getdata(url): 
    r = requests.get(url) 
    return r.text

第 3 步：现在将电台名称和电台代码合并到 URL 中，并将 URL 传递到 getdata()函数并将该数据转换为 HTML 代码。

# input by geek
from_Station_code = "NDLS"
from_Station_name = "DELHI"
  
To_station_code = "PNBE"
To_station_name = "PATNA"
# url
url = "https://www.railyatri.in/booking/trains-between-stations?from_code="+from_Station_code+"&from_name="+from_Station_name+"+JN+&journey_date=+Wed&src=tbs&to_code=" + \
    To_station_code+"&to_name="+To_station_name + \
    "+JN+&user_id=-1603228437&user_token=355740&utm_source=dwebsearch_tbs_search_trains"
  
# pass the url
# into getdata function
htmldata = getdata(url)
soup = BeautifulSoup(htmldata, 'html.parser')
  
# display html code
print(soup)

输出：

第 4 步：现在从 HTML 代码中找到所需的标签并遍历结果。

# find the Html tag
# with find()
# and convert into string
data_str = ""
for item in soup.find_all("div", class_="col-xs-12 TrainSearchSection"):
    data_str = data_str + item.get_text()
result = data_str.split("\n")
  
print("Train between "+from_Station_name+" and "+To_station_name)
print("")
  
# Display the result
for item in result:
    if item != "":
        print(item)

输出：

全面实施。
