Example code of a Chinese verification code randomly generated by Python

Python randomly generates the instance code of the Chinese verification code. if you need it, refer to the python code.

The code is as follows:

#-*-Coding: UTF-8 -*-

Import Image, ImageDraw, ImageFont

Import random

Import math, string

Class RandomChar ():

"Used to randomly generate Chinese characters """

@ Staticmethod

Def Unicode ():

Val = random. randint (0x4E00, 0x9FBF)

Return unichr (val)

@ Staticmethod

Def GB2312 ():

Head = random. randint (0xB0, 0xCF)

Body = random. randint (0xA, 0xF)

Tail = random. randint (0, 0xF)

Val = (head <8) | (body <4) | tail

Str = "% x" % val

Return str. decode ('Hex'). decode ('gb2312 ')

Def randRGB (self ):

Return (random. randint (0,255 ),

For I in range (0, num ):

Draw. line ([self. randPoint (), self. randPoint ()], self. randRGB ())

Del draw

Def randChinese (self, num ):

For I in range (0, num ):

X = start + self. fontSize * I + random. randint (0, gap) + gap * I

Def save (self, path ):

Call method

The code is as follows:

Ic = ImageChar (fontColor = (100,211, 90 ))

Ic. randChinese (4)

Ic. save ("1.jpeg ")
