Python enumerate() tqdm progress-bar when reading a file?

To combine enumerate() and tqdm for displaying a progress bar while reading a file, you can achieve this by iterating over the file lines with enumerate() and using tqdm to visualize the progress. Here's how you can do it:

First, make sure you have tqdm installed:

pip install tqdm

Then, you can create a script to read the file and display a progress bar using tqdm:

from tqdm import tqdm file_path = 'your_file.txt' with open(file_path, 'r') as file: # Get the total number of lines in the file total_lines = sum(1 for line in file) # Reopen the file for reading with open(file_path, 'r') as file: for line_number, line in tqdm(enumerate(file, start=1), total=total_lines, desc="Reading"): # Process each line here # ... # The tqdm progress bar will be displayed while reading the file

In this example, we first open the file to count the total number of lines using a generator expression with sum(). Then, we reopen the file for reading and use enumerate() along with tqdm to iterate over the lines while displaying a progress bar. The total argument in tqdm specifies the total number of iterations, which is the total number of lines in the file.

Replace 'your_file.txt' with the path to your file. Inside the loop, you can process each line as needed.

This code will display a progress bar using tqdm while reading the file, allowing you to see the progress as each line is processed.
