What three steps must be taken by a program when it uses a file?

Solution Preview

Three steps that must be taken when a file is used by a program:

  1. Open a file
  2. Process the file
  3. Close the file
  4. Open a file

The built-in "open()" function is used to open a file. This open() function will return a file object, and is generally used with two arguments. The first argument is the name of the file that we intend to open and second argument specifies the mode of the operation to be performed on the file.

The following syntax is used to open a file:

variable_name = open("filename", "mode")

"variable_name" is the name of the variable for file object.

"open()" is a keyword used to open a file.

"filename" is a name of the file and it should be specified as a "string".

"mode" is used to specify the mode for performing file operations such as read, write, and append.
