Reading Files with Open

 we'll use Python's built-in open() function to create a file object and retrieve data from a text file (txt). Here's how it works:

1. We can use the open() function to obtain a file object. The function takes two parameters: the file path (which includes the file name and directory) and the mode in which to open the file. Common modes include 'r' for reading, 'w' for writing, and 'a' for appending. We'll use 'r' for reading.

2. Once we have the file object, we can retrieve information about the file. For example, we can use the name attribute to get the name of the file, and the mode attribute to see which mode the file object is in.

3. It's important to always close the file object using the close() method to free up system resources. However, using the with statement is a better practice because it automatically closes the file when the block of code inside it finishes execution.

4. We can read the contents of the file using various methods like read(), readlines(), or readline().

5. The read() method reads the entire contents of the file and stores it as a string.

6. The readlines() method reads each line of the file and stores them as elements in a list. Each element corresponds to one line of the file.

7. The readline() method reads the next line of the file each time it's called.

8. We can iterate over the lines of the file using a loop to print each line individually.

9. Additionally, we can specify the number of characters we'd like to read from the file as an argument to the readlines() method.

Overall, these methods allow us to efficiently read and process data from text files in Python. For more examples and information about methods and other file types, you can refer to the provided labs.
