Overview

通过python api向postgresql存入数据出现重复数据，会报错IntegrityError，如何捕捉？
Solution

通过sqlalchemy使用Python API。

The sqlalchemy wraps the psycopg2 exception to its own exception.
```
from sqlalchemy.exc import IntegrityError
try:
    ...
except IntegrityError as e:
    print("right")
```
References

Why is psycopg2 IntegrityError not being caught?
