Learn Python first
If you want to work as a network engineer, learn Python. Not Java. Not C++. Not five languages at once. Python is the one that shows up beside CCNA skills in automation teams, cloud network teams, and Cisco’s own training for engineers who already understand devices.
The rest of the order is Bash, then Ansible, then Go only if your job starts to look like software. Networking itself stays the main subject. A beautiful script that pushes a wrong subnet is still an outage.

1. Python
Python wins because network data is messy text, JSON, and APIs, and Python is direct about all three. A junior script usually does one of these:
- Log in to a switch, run a show command, save the output
- Read a CSV of sites and report which VLANs are missing
- Call a cloud or controller API and print the routes
Libraries you will actually meet: Netmiko or NAPALM for devices, requests for APIs. The Python docs cover the language. They will not teach you VLANs. Do that in CCNA or network administration class, and use Python training for the language half only.
You do not need data-science Python. Pandas can wait. So can Django.
2. Bash
Network engineers spend hours on Linux jump hosts. Bash is how you grep a log, loop a ping, and move a file without opening an editor. Learn it beside Python, in small pieces:
- Pipes, grep, and awk or cut for columns
- SSH config and keys
- A short for-loop that pings a list of gateways
Bash is a poor place to build a large automation system. When the script grows past a page, move it to Python so someone else can test it.
3. Ansible, after the first scripts
Ansible is not a general-purpose language. Playbooks are YAML, with Jinja templates when the config changes per site. Indian infrastructure teams like it because a reviewer can see the intended VLAN without reading a long program.
Learn Ansible when both of these are true: you can configure the change by hand, and you have broken a Python script often enough to want a safer pattern. The Ansible documentation is the reference. A classroom path is Ansible training, ideally after Python basics rather than instead of them. DevOps training is the neighbouring skill if your target team treats the network as code.
4. Go, later
Go appears in newer network software: some controllers, collectors, and open-source tools. It is fast and strict. It is a bad first language for a student who still needs to learn OSPF. Pick it up in year three or four if your team writes services, not if you are trying to clear a fresher NOC interview.
Languages to skip at the start
| Language | Why people mention it | What to do |
|---|---|---|
| Java | Common in Indian software hiring | Skip unless you change career to development |
| C or C++ | Used deep in device operating systems | Skip. You will not write IOS in your first job |
| JavaScript | Web dashboards | Skip until a team asks for a portal |
| Go | Modern network tooling | Learn after Python, only if the role needs it |
A practical order for students
- Subnetting, VLANs, and a lab you can rebuild.
- Python: files, loops, JSON, one device login.
- Bash on Linux, enough to live on a server.
- Ansible for one standard change, such as a VLAN template.
- Only then, look at Go or cloud APIs in more depth. The coding-depth question is answered in does a network engineer need coding skills.
Interviewers notice when the language and the network topic match. “I automated a backup of running-config” beats “I completed three languages.” If you want that project scoped to a batch, compare the Python and CCNA syllabi before you pay for both at once.
