How do I manage Python dependencies in Travis CI?

You can manage Python dependencies in Travis CI by specifying them in your requirements.txt file and using the pip command in your .travis.yml file.

Can you show me an example of a .travis.yml file?

Sure! Here's a simple example:

language: python
python:
  - "3.8"
install:
  - pip install -r requirements.txt
script:
  - pytest

What if I have multiple Python versions to test against?

You can specify multiple Python versions in the python section of your .travis.yml file like this:

python:
  - "3.6"
  - "3.7"
  - "3.8"

How can I cache my dependencies to speed up builds?

You can cache your dependencies by adding a cache section in your .travis.yml file:

cache:
  pip: true
