How to implement travel cost calculation function using Python and Baidu Map API

Method of using Python and Baidu Map API to implement travel cost calculation function

In modern society, travel has become an indispensable part of people's lives. With the development of science and technology, people's demand for travel is getting higher and higher. They not only pursue convenience and comfort, but also hope to get more economic protection. Therefore, the travel cost calculation function has become a very important requirement.

Python, as a high-level programming language, is widely used in various fields. Baidu Map API is currently one of the most popular map APIs, providing a wealth of geographical information services. Combining Python and Baidu Map API, we can easily implement the travel cost calculation function.

First, we need to install the Python map API library. Through the pip install baidu-aip command, we can install the Python SDK of Baidu Map API.

Next, we need to obtain the developer key (AK) of Baidu Map Open Platform. After registering a developer account on Baidu Maps Open Platform, you can obtain AK by creating applications. Save the AK in the code for subsequent API calls.

The following is a sample code that uses Baidu Map API and Python to implement travel cost calculation:

from baidu.aip import AipMap

# 百度地图API的开发者密钥
APP_ID = 'your_app_id'
API_KEY = 'your_api_key'
SECRET_KEY = 'your_secret_key'

# 初始化百度地图API客户端
client = AipMap(APP_ID, API_KEY, SECRET_KEY)

# 出行起点和终点的经纬度
start_lng = 116.397477
start_lat = 39.908692
end_lng = 116.410049
end_lat = 39.916025

# 获取驾车路线
driving_route = client.direction_driving(start_lng, start_lat, end_lng, end_lat)

# 提取驾车路线的距离和时间
distance = driving_route['result']['routes'][0]['distance']
duration = driving_route['result']['routes'][0]['duration']

# 计算出行费用（示例中以每公里0.5元计算）
fare = distance * 0.5

# 输出结果
print('出行距离：{}公里'.format(distance))
print('出行时间：{}分钟'.format(duration))
print('出行费用：{}元'.format(fare))

In the above code, first we initialize the client of Baidu Map API, and then call direction_drivingMethod to obtain driving route information. Next, we extract the distance (distance) and time (duration) of the trip from the returned route information. Finally, according to the set fare standard, the travel fee (fare) is calculated and the result is output.

It should be noted that in actual applications, we can call other Baidu Map API interfaces according to specific needs, such as bus route planning, walking route planning, etc., to meet the cost calculation needs of different travel modes.

To sum up, it is very simple to use Python and Baidu Map API to implement the travel cost calculation function. Through this method, we can easily calculate travel costs and provide better reference and guarantee for people's travel. Moreover, based on the rich functions of Baidu Map API, we can further expand the travel cost calculation function to adapt to more diversified travel needs.
