object of type 'map' has no len()-CodePudding

I tried to run my docker image for my django project and I have got a error:

I tried to use different version of python but always same issue back to me!

Here my docker file

FROM python:3

RUN pip install --upgrade pip

ENV PYTHONUNBUFFERED 1
RUN mkdir /code
WORKDIR /code
COPY . /code/
RUN pip install -r requairements.txt


EXPOSE 8000

CMD ["gunicorn", "--chdir", "Eventful-main", "--bind", ":8000", "eventful.wsgi:application"]

Check the answer from Object of type 'map' has no len() in Python 3

"In Python 3, map returns a map object not a list. You can convert it into a list then get the length from there:

>>> print(len(list(L)))
10

In your case:

if len(list(version_info)) != 3:

CodePudding user response：

print(len(map.keys()))

You can use the length of the key in the map to calculate the length of the map
