Which method helps in reading all lines from a file until the end?

The method that effectively reads all lines from a file until the end is indeed designed to retrieve each line in a list format, making it convenient for processing multiple lines at once. When you use the readlines() method, it reads the entire content of the file and returns a list where each element corresponds to a line in the file. This approach is particularly useful when you want to handle the data line by line, since you can easily iterate over the list afterward to perform additional operations on each line.

The other methods, while useful in their own contexts, do not read all lines to completion in the same way. The read() method retrieves all the contents of the file as a single string, which is not ideal for scenarios where line-by-line processing is needed. The readline() method reads a single line at a time from the file, which requires additional calls to read multiple lines sequentially. The getlines() method is not a standard method in Python for file operations and therefore would not function as expected.

Thus, readlines() is specifically tailored for the task of reading all lines from a file until the end and providing them in a format that is easy to work with.
