How to read files and output?

In Python, you can use the open() function to open a file, and then use the read() method to read the file contents.

Detailed steps:

1. Open the file:

   <code class="python">file = open("my_file.txt", "r")</code>

   Among them:

2. "my_file.txt" is the path of the file to be opened.
3. "r" means opening the file in read-only mode.

4. Read file content:

   <code class="python">file_content = file.read()</code>

   This line of code reads the entire file content into the file_content variable.

5. Output file content:

   <code class="python">print(file_content)</code>

   This line of code will print the file content in the console.

6. Close the file:

   <code class="python">file.close()</code>

   After reading the file, be sure to close the file to release resources.

Full example:

<code class="python">with open("my_file.txt", "r") as file:
    file_content = file.read()
    print(file_content)</code>

Use the with statement to simplify your code by automatically closing the file at the end of the block.
