For Python3:

FROM ubuntu:latest
WORKDIR /app
ADD . /app
RUN set -xe \
    && apt-get update \
    && apt-get install python3-pip
RUN pip3 install --upgrade pip
RUN pip3 install -r requirements.txt

Thats it :-)

You have to install pip first.

FROM iron/python:2.7
WORKDIR /app
ADD . /app
RUN set -xe \
    && apt-get update \
    && apt-get install python-pip
RUN pip install --upgrade pip
RUN pip install -r ./requirements.txt
