How to read data from files?

To read data from files in Python, you can use several methods depending on the file format. Here are examples for reading text files and CSV files:

You can use the built-in open() function:

with open('data_file.txt', 'r') as file:
    data = file.read()
    print(data)

If you're working with CSV files, you can use the pandas library:

import pandas as pd

df = pd.read_csv('test_file.txt')  # Adjust the filename as needed
print(df)

If you want to read numerical data from a text file, you can use NumPy:

import numpy as np

data = np.loadtxt('data_file.txt', delimiter=',')  # Adjust delimiter as needed
print(data)

Choose the method that best fits your file type and data structure! If you need further assistance, feel free to ask.
