A Python Function for Removing Duplicate Lines
Dealing with text files is a common task for programmers, data scientists, and anyone who works with data. Often, these files can contain duplicate lines, which can be a nuisance when you're trying to analyze or process the information. Manually removing duplicates can be tedious and error-prone, especially for large files. Fortunately, Python offers a simple and efficient way to automate this process.
In this blog post, I'll share a Python function that reads a text file, removes duplicate lines, and writes the unique lines to a new file. This can save you significant time and effort, and ensure the accuracy of your data.
The Python Solution
def remove_duplicate_lines(input_file, output_file): """ Removes duplicate lines from a text file. Args: input_file: Path to the input text file. output_file: Path to the output text file (containing unique lines). """ try: with open(input_file, 'r') as infile: lines = infile.readlines() unique_lines = …
