I've read the opencv-python-toturial and saw a example as below:

import numpy as np
import cv2
img = cv2.imread('tsukuba_l.png',0)
# create a CLAHE object (Arguments are optional).
clahe = cv2.createCLAHE(clipLimit=2.0, tileGridSize=(8,8))
cl1 = clahe.apply(img)
cv2.imwrite('clahe_2.jpg',cl1)

I've installed opencv but cannot find the cv2.createCLAHE method, is this a bug? My opencv version is 2.4.2 and Python 2.7.5.

"My opencv version is 2.4.2" - there is your problem.

there is no CLAHE in 2.4.2, to use it, you will have to update.

hmm, 3.0 only if you want to try the alpha version. (there are a couple of hiccups currently)

unless you're out for adventure, consider 2.4.10 (the stable release) for now
