Which statement opens a text file so that you can retrieve the information it contains?

vesna_86 [32]

Answer:

Answered below

Explanation:

aFile = open("books.txt", "r")

This code uses the function open() which takes two parameters. The first parameter is the file name while the second parameter is the mode in which you are accessing the file.

The "r" mode opens the file in a reading state. That is, you can only read from the file. This code completes the reading process

aFile.read( )

The "w" mode opens the file so you can write to it and make changes.

The "a" mode opens the file so you can add contents to it.
