I want to find a easy-to-use OCR python module in linux, I have found pytesser http://code.google.com/p/pytesser/, but it contains a .exe executable file.

I tried changed the code to use wine, and it really works, but it's too slow and really not a good idea.

Is there any Linux alternatives that as easy-to-use as it?

You can just wrap tesseract in a function:

import os
import tempfile
import subprocess

def ocr(path):
    temp = tempfile.NamedTemporaryFile(delete=False)

    process = subprocess.Popen(['tesseract', path, temp.name], stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    process.communicate()

    with open(temp.name + '.txt', 'r') as handle:
        contents = handle.read()

    os.remove(temp.name + '.txt')
    os.remove(temp.name)

    return contents

If you want document segmentation and more advanced features, try out OCRopus.
