Answer 1

Reading data from a file in Python involves opening the file, reading its contents into a Python-compatible format, and then closing the file properly. Common methods used include read(), readline(), and readlines() for data retrieval.

Step-by-step explanation:

The question relates to the task of reading data from a file using the Python programming language. In Python, this can typically be done by opening a file in a reading ('r') mode using the open() function. Once the file is opened, you can read the contents using methods like read(), readline(), or readlines(). These methods help to convert the data from the file into a format that Python can work with. After processing the data, it is important to close the file using the close() method to free up system resources.

Here's a basic example of reading a file in Python:

# Open a file in read mode
file = open('data.txt', 'r')
# Read the contents of the file
content = file.read()
# Close the file
file.close()

Remember to handle potential errors using try-except blocks and consider using the with statement to automatically close the file after you are done processing it.
