In Python, reading a file object involves opening the file, reading its content, and then closing the file. The file object can be opened in various modes such as reading, writing, and appending.

To read a file object in Python, you can use the open() function to open the file in read mode. Here's an example of how to do this:

```

with open('example.txt', 'r') as file:

content = file.read()

print(content)

```

In this example, we open the file 'example.txt' in read mode and use the read() method to read its content. The with statement is used to ensure that the file is properly closed after its suite finishes, even if an exception is raised. This ensures that the file is always closed, even if an error occurs while processing the file.

You can also read a file line by line using the readline() method. Here's an example:

```

with open('example.txt', 'r') as file:

for line in file:

print(line)

```

This code snippet opens the file 'example.txt' and iterates through each line using a for loop.

If you want to read a JSON file, you can use the json module to easily read and parse JSON data. Here's an example:

```

import json

with open('data.json', 'r') as file:

data = json.load(file)

print(data)

```

In this example, we open the file 'data.json' and use the json.load() function to load the JSON data from the file into a Python dictionary.

It's important to always close the file after reading its content to free up system resources. The with statement in Python is a good practice to ensure that files are properly closed after they are used.

In summary, reading a file object in Python involves opening the file, reading its content, and then closing the file. Whether you want to read a plain text file or a JSON file, Python provides simple and powerful tools to accomplish this task with ease.
