I. Introduction to Tesseract
Tesseract is an OCR Library (OCR is short for Optical Character Recognition). It is used to scan text files, analyze and process image files, and obtain text and layout information,

method to deal with indentation, but this increases the amount of code after all. Another method is to modify the existing code, in this way, we do not need to do repetitive work.
But how can we control the current print_lol method to implement nested indentation of the list? One way is to use additional parameters to control the print behavior, but what kind of parameters are added? In Python, we provide a built-in function: range ()
