How to use Python to randomly generate Picture Verification Code

This article mainly explains "how to use Python to randomly generate picture verification code", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Now let the editor take you to learn "how to use Python to randomly generate picture verification code"!

Import module

Import randomfrom PIL import Image,ImageFont,ImageDraw

Generate random verification code

Def rndtxt (): txt_list = [] # uppercase letter txt_list.extend ([i for i in range (65 txt_list 90)]) # lowercase letter txt_list.extend ([i for i in range (97123)]) # numeric txt_list.extend ([i for i in range (48,557)]) return chr (txt_ list.Randint (0LN (txt_list)-1)])

As the background color and font color of the picture to be generated later.

Def rndbgcolor (): # background color return (random.randint (64255), random.randint (64255), random.randint (64255)) def rndtxtcolor2 (): # font color return (random.randint (32127), random.randint (32127), random.randint (32127))

Generate the print CAPTCHA and open it in the form of a picture. Do not save the picture file, but only for temporary CAPTCHA verification

Def code (): weight = 240hight = 60 image = Image.new ('RGB', (weight,hight), (255255255)) font = ImageFont.truetype (' msyh.ttc',36) draw = ImageDraw.Draw (image) # fill background color for x in range (weight): for y in range (hight): draw.point ((xQuery) Fill=rndbgcolor () # generate random verification code for T in range (4): rndtxt_2 = rndtxt () print (rndtxt_2) # print the value of the verification code draw.text ((60 * T + 10), rndtxt_2,font=font,fill=rndtxtcolor2 ()) image.show ()
