Tips

pyATS Tip: Use Genie Diff to compare structured data and easily identify differences. It works with dictionaries, including structured output from Genie Parse and Genie Learn. Below is an example of using Genie Diff to compare the results of a Genie Parse command: from genie.utils.diff import Diff from

🐍 Python Tip: Speed up your Python package installs by up to 100x using uv, a drop-in replacement for pip. # Using pip ❌ pip install -r requirements.txt pip install netmiko # Using uv - faster by up to 100x ✅ pip install uv uv pip install -r requirements.txt uv pip install netmiko

Git Tip: git checkout allows you to restore a single file to a previous version without affecting the rest of your project. For example: git checkout--. Full example below: # View the commit history of a specific file. git log -- path/to/file # Restore a specific file to its state

Git Tip: Skip --set-upstream! Set the upstream branch automatically using the push.default config. Heres an example: # Before: Manually setting upstream git push --set-upstream origin apples # Configuration to set upstream automatically git config --global push.default current # After: Just push, and Git sets the upstream automatically git push

Jinja Tip! Use selectattr to filter a list of dictionaries based on a matching condition. # Input data interfaces: - { device: 'spine1', interface: 'GigabitEthernet0/0', ip: '10.1.1.1' } - { device: 'spine1', interface: 'GigabitEthernet0/1', ip: '10.1.2.

Jinja Tip: Use Jinja's map to extract specific values from a list of dictionaries. Perfect for pulling out IPs, interfaces, or other attributes within your Jinja templates or Ansible playbooks. Example below: # Input data interfaces: - { device: 'spine1', interface: 'GigabitEthernet0/0', ip: '10.

git diff lets you compare changes between commits, branches, or specific files. It also offers options for summaries and detailed file changes. Here are a few examples: # Compare Changes Between Commits git diff <commit1> <commit2> # Compare changes between two commits. git diff <commit1> <

When troubleshooting Ansible settings, use ansible-config dump --only-changed to show only configurations that differ from the default. It reveals the source of the change, whether it's from a config file or an environment variable. Here's an example 👇 $ ansible-config dump --only-changed # Output: # CONFIG_FILE() = /home/rick/ansible-examples/

pyATS Tip: Use pyATS APIs, like get_platform_memory_usage() , to easily retrieve device performance metrics, such as memory usage, from network devices, which you can later use within your test cases. Example below 👇 from genie import testbed testbed = testbed.load("testbed.yml") device = testbed.devices["leaf1&
