How to Easily Import Data from Notepad to a Python Dictionary with Netmiko

If you've ever struggled with importing data from a plain text file into a Python dictionary, you're not alone! Many developers encounter the challenge of converting structured data to a format that can be easily manipulated in their code. This guide will walk you through the process of importing a list of devices (IP addresses, usernames, and passwords) from a Notepad file into a Python dictionary. We'll do this step by step, ensuring you know exactly what to do and why.

The Problem

Imagine you have a Notepad file containing device data in the following format:

Once this dictionary is created, you'll be able to use Netmiko library to connect to each device sequentially.

The Solution

Step 1: Set Up Your Environment

First, ensure you have your environment set up. You need Python installed on your machine and the Netmiko library. If you haven't installed Netmiko yet, you can do so with this command:

Step 2: Read Data from the Notepad File

Next, you'll want to write some code to read the contents of the Notepad file. Below is a refined version of your initial code that accomplishes this task.

Step 3: Split and Organize Data

Once the data is read, it needs to be split into manageable chunks. Each line can be divided into a list of strings where each element represents a different piece of information (IP, username, password). Here's how to do that:

Step 4: Create a Dictionary for Each Device

After splitting the data into lists, you can construct a dictionary for each device. The following loop checks if a line contains both username and password; if not, it assigns default values.

Step 5: Connect to Devices with Netmiko

Now that you have your network_dict, you can use it to connect to devices using Netmiko. Just make sure to uncomment the connection part in the loop where needed.

Conclusion

In this guide, we demonstrated how to take data from a Notepad file and import it into a Python dictionary. By organizing the information in a structured format, you can easily connect to devices using the Netmiko library. Remember to handle any exceptions and tailor the default names and passwords to fit your needs. Happy coding!
