Read Files

Reading files is a common operation in programming for processing and analyzing data from external sources. In Python, you can use the open() function to open a file and read its contents.

Reading Text Files

To read the contents of a text file, you can use the read() method after opening the file in read mode ('r'). For example:

with open('example.txt', 'r') as file:
    content = file.read()
    print(content)

Reading CSV Files

For reading CSV (Comma Separated Values) files, you can use the csvmodule in Python. For example, to read a CSV file and print its rows:

import csv

with open('data.csv', 'r') as file:
    csv_reader = csv.reader(file)
    for row in csv_reader:
        print(row)

Conclusion

Reading files is a fundamental operation in Python for working with external data. By understanding how to read text and CSV files, you can process and analyze data from files in your Python programs.
