What library to use to extract text from images (OCR)? [closed]

I need to recognize text in images (OCR). What library can I use in Python to extract text from the images?

How do I extract the exact text from an image?

OCR is the “Optical Character Recognition” technology used to convert any image containing handwritten or printed readable text. Once the file has been processed through the online OCR, the extracted text can be further edited by using word processing software like MS Word.

Check out google tesseract-oct, which has it's own python module.
