data = open(file, encoding='utf-8')

This line of code opens a file in Python and specifies that the file should be treated as UTF-8 encoded text. The variable "file" should contain the file name or path to the file that you want to open. The "encoding='utf-8'" argument ensures that any non-ASCII characters in the file will be properly interpreted by Python. Once the file is opened, you can read its contents using various methods such as read(), readline(), or readlines().
