Assuming your file structure is the below:

Dockerfile: (note WORKING DIR)

FROM python:3.6.5-slim
RUN mkdir -p /home/project/bottle
WORKDIR /home/project/bottle 
COPY requirements.txt .
RUN pip install --upgrade pip --no-cache-dir -r requirements.txt
COPY . .
CMD ["python", "app.py"]

Docker Compose:

version: '3'

services:
  web:
    container_name: web
    volumes:
      - './web:/home/project/bottle/'  <== Local Folder:WORKDIR
    build: ./web
    ports:
      - "8080:8080"
