preface

When we collect data , Too fast or frequently visited , Or you can pop up the verification code as soon as you visit , And then the clam bead ~

Today, I will give you a simple method to deal with the verification code

Environment module

There needs to be a ddddocr modular , This is something that someone else has written open source , Simple and easy to use , But the accuracy is a little poor , But it is still very easy to use .

If you want precision , You can call some written by others API .

Let's just win+r Enter... After the search box pops up cmd , Click OK to pop up the command prompt window , Input pip install ddddocr You can install .

If not, please refer to my top article for detailed explanation .

Code display

Not much code , It's simple .

After the module is installed, let's import it ：

import ddddocr

Then instantiate , Use one cor Receive this data .

ocr = ddddocr.DdddOcr()

I have prepared four verification codes here ：

First of all, we use with open To read this file , The read mode uses rb , If it is a picture, read its binary data

with open('img_3.png', 'rb') as f:

Use f.read() Read the data out , Then customize a variable to receive .

img_bytes = f.read()

And then we passed classification Pass it in , Just print out the results .

result = ocr.classification(img_bytes)print(result)

Realization effect ：

Pure digital

Letter + Digital

You can see that they are completely identified , Even if there are some fancy horizontal lines on it .

Complete code

import ddddocrocr = ddddocr.DdddOcr()with open('img_3.png', 'rb') as f: img_bytes = f.read()result = ocr.classification(img_bytes)print(result)

You can try it yourself , It can also be directly applied to the practice of data collection ~
