What programming language do you usually use for your projects?

In my projects, I usually use a programming language that best fits the task and infrastructure. In the context of DevOps, this often includes:

• Python — due to its simplicity, a large number of libraries for automation, working with APIs, scripting, and tools.
• Bash — for writing automation scripts at the operating system level.
• Go — for creating high-performance and cross-platform utilities.

For example, for automating deployment and infrastructure management, I often write scripts in Python using libraries like paramiko for SSH or boto3 for AWS.

Here's an example of a simple Python script for SSH connection:

import paramiko

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('hostname', username='user', key_filename='/path/to/key')
stdin, stdout, stderr = ssh.exec_command('ls -l')
print(stdout.read().decode())
ssh.close()
