+## Python - pip
+
+For pip, the cache directory will vary by OS. See https://pip.pypa.io/en/stable/reference/pip_install/#caching
+
+Locations:
+ - Ubuntu: `~/.cache/pip`
+ - Windows: `~\AppData\Local\pip\Cache`
+ - macOS: `~/Library/Caches/pip`
+
+### Simple example
+```yaml
+- uses: actions/cache@v1
+  with:
+    path: ~/.cache/pip
+    key: ${{ runner.os }}-pip-${{ hashFiles('**/requirements.txt') }}
+    restore-keys: |
+      ${{ runner.os }}-pip-
+```
+
+Replace `~/.cache/pip` with the correct `path` if not using Ubuntu.

+### Multiple OS's in a workflow
