How do you read a file in Python?

To read a file in Python, the correct approach involves utilizing the open() function along with methods such as read(), readline(), or readlines(). The open() function is essential as it establishes a connection to the file you want to read, specifying the mode (such as 'r' for reading). Once the file is opened, you can use these methods to extract the file's content.

The read() method reads the entire content of the file and returns it as a single string. The readline() method reads one line at a time, allowing for more controlled data processing, especially in larger files. The readlines() method retrieves all lines in the file and returns them as a list of strings, where each line corresponds to an item in the list.

In contrast, options that mention using the input() function are not applicable for file reading; input() is used for taking input from the user via the console. Similarly, using the write() function is intended for writing data to a file rather than reading it. Relying solely on the read() function without open() is also insufficient, as the function requires an associated file object created by open() to work effectively. Thus, the combination of open() with appropriate reading methods is the correct way
