Solution

The correct way to open a file in Python for reading is:

file = open("file.txt", "r+")

This command opens the file for both reading and writing. However, if you only want to open the file for reading, you should use:

file = open("file.txt", "r")

Here's what the different modes mean:

  • "r" - Read - Default value. Opens a file for reading, error if the file does not exist
  • "a" - Append - Opens a file for appending, creates the file if it does not exist
  • "w" - Write - Opens a file for writing, creates the file if it does not exist
  • "x" - Create - Creates the specified file, returns an error if the file exists

In addition to these, you can specify if the file should be handled as binary or text mode

  • "t" - Text - Default value. Text mode
  • "b" - Binary - Binary mode (e.g. images)
