Converting a List of Words into a Dictionary in Python

If you’ve recently found yourself working with a large text file containing hundreds of thousands of words, you may be wondering how to manipulate this data in Python. You might think about creating a dictionary to work with these words, but in fact, a simple list is often the right choice for tasks such as measuring word lengths or performing various analyses.

In this guide, we will walk you through the process of converting a list of words from a text file to a Python list, and how to manipulate that list for your programming needs.

Understanding Your Data Format

When dealing with a text file (let’s say words.txt) where each word is listed on a new line, your data resembles the following:

This structure is straightforward to use; each line represents a different word. While you initially considered using a dictionary, remember that dictionaries in Python are meant for key-value pairs. Since we just have words and no associated values, a list is sufficient.

Steps to Convert Your Text File into a List

To get started, let’s cover the steps to read from your text file and convert it into a list of words that you can easily manipulate within your Python program.

Step 1: Opening the File

First, you need to open your text file in read mode. Here’s how you can do it:

In the code snippet above:

open('words.txt', 'r') opens the specified text file.

The with statement ensures that the file is properly closed after its suite finishes.

The list comprehension word.strip('\n') for word in file.readlines() reads each line of the file, strips out the newline character at the end, and creates a list of words.

Step 2: Processing the List

Now that you have your word_list, you can easily perform operations, such as calculating the length of each word and printing it to another file. Here’s how you can do that:

In this full example:

We open a new file called LengthOutput.txt in append mode ("a").

For each word in word_list, we calculate its length using the len() function.

Finally, we output the word along with its length to the new file.

Conclusion

In summary, while working with a sizeable list of words contained in a text file, remember that using a list is often more suitable than attempting to convert it into a dictionary. This approach simplifies data operations, making it easier to analyze and manipulate as needed.
