🐍 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&

Ansible Resource Modules offer various states to manage network configuration sections effectively. For example use parsed to convert configurations into structured data, like so: --- - name: Ansible Modules - Resource Modules (Parse) hosts: leaf1 gather_facts: false tasks: - name: Parse the provided configuration cisco.ios.ios_l3_interfaces:
