There are quite a lot of concerts recently, all of which are well-known singers that everyone likes, so I specially made a tutorial to help everyone (mainly because my cousin wants to chase after the goddess, so I taught him to grab tickets by himself)
knowledge points
- Selenium Taobao slider processing
- Realization of buying logic
Necessary environment
- python 3.8
- pycharm professional edition
- Google Chrome + Google Drive + selenium3.141.0
- stealth.min.js
code display
I also recorded a video to explain in detail, packaged it together with the source code, and sent me a private message to receive it automatically.

from selenium import webdriver
Get the moving trajectory, imitate the sliding behavior of people, first accelerate and then decelerate uniformly.
def get_tracks(distance):
# 初速度
v = 5
# 单位时间为0.2s来统计轨迹，轨迹即0.2内的位移
t = 0.2
# 位移/轨迹列表，列表内的一个元素代表0.2s的位移
tracks = []
# 当前的位移
current = 0
# 到达mid值开始减速
mid = distance * 4 / 5
while current < distance:
if current < mid:
# 加速度越小，单位时间的位移越小,模拟的轨迹就越多越详细
a = 8
else:
a = -3
# 初速度
v0 = v
# 0.2秒时间内的位移
s = v0 * t + 0.5 * a * (t ** 2)
# 当前的位置
current += s
# 添加到轨迹列表
tracks.append(round(s))
# 速度已经达到v,该速度作为下次的初速度
v = v0 + a * t

Click here to get it for free: CSDN spree: "Python learning route & full set of learning materials" free sharing
1. Learning routes in all directions of Python
The technical points in all directions of Python are sorted out to form a summary of knowledge points in various fields. Its usefulness lies in that you can find corresponding learning resources according to the above knowledge points to ensure that you can learn more comprehensively.
2. Essential development tools for Python
4. Python video collection
Watching the zero-based learning video is the fastest and most effective way to learn. Following the teacher's ideas in the video, it is still very easy to get started from the basics to the in-depth.
5. Practical cases
Optical theory is useless, you have to learn to follow along, and you have to do it yourself, so that you can apply what you have learned to practice. At this time, you can learn from some actual combat cases.
6. Python exercises
Check the learning results.
7. Interview materials
We must learn Python to find high-paying jobs. The following interview questions are the latest interview materials from first-line Internet companies such as Ali, Tencent, and Byte, and Ali bosses have given authoritative answers. After finishing this set The interview materials believe that everyone can find a satisfactory job.
