Preface

python Two very important functions are provided to deal with python Exceptions and errors in the operation of the program . You can use this function to debug python Program

Novice reminder

When a novice writes code , We often encounter code errors , Many of my friends are not good at English , I don't know what it means to report an error ？ Now we are sorting out an exception type

If the software is tested 、 The interface test 、 automated testing 、 Continuous integration 、 The interview experience . If you are interested, you can go to 893694563, There will be test data sharing within the group from time to time . There will also be technology bulls , Share technology with peers in the industry
