python - Github Action flake8 失败 : f-string is missing placeholders

Question

按照“FastAPI-TDD with Docker”类(class)，我让项目在本地构建和传递，然后在 github 操作中失败:
来源中的进攻线似乎是:

    response = test_app_with_db.get(f"/summaries/")

Github Action 结果是:

Run docker exec fastapi-tdd python -m flake8 .
  docker exec fastapi-tdd python -m flake8 .
  shell: /bin/bash -e {0}
  env:
    IMAGE: docker.pkg.github.com/$GITHUB_REPOSITORY/web
./app/db.py:14:1: E303 too many blank lines (3)
./tests/test_ping.py:4:1: F401 'app.main' imported but unused
./tests/test_summaries.py:6:1: F401 'pytest' imported but unused
./tests/test_summaries.py:60:37: F541 f-string is missing placeholders
##[error]Process completed with exit code 1.

Answer 1

f 字符串与占位符一起使用
例子 :
如果您想将 '/summary/' 放在 f 字符串中，请将其分配给某个变量，然后将该变量放在占位符中
语法是

f'{variable}'

例子 :

f'{"quoted string"}'
