Python generates a verification code

1. Get random string

2. Introduce PIL packages, create canvases,
3. To create a font, you need to use imagefont.truetype
4. Get random background color and font color
5. Write the text to the image
6. Save picture

The code is as follows:

Import Random

Import Image,imagefilter

Import Imagefont

Import Imagedraw

#获取随机字符串

def getchar (len=6):

#新建元组存储获得的字符串

Codelist=[]

For I in range: #获取数字

Codelist.append (str (i))

For I in Range (65,91): #获取A-Z Letters

Codelist.append (str (i))

For I in Range (97,123): #获取a-Z Letters

Codelist.append (str (i))

Code=random.sample (Codelist,len) #截取len个字符, returns a tuple

Verification= '. Join (code) #将元组合并成字符串

Return verification

#创建画布

Im=image.new (' RGB ', (240,60), (255,255,255))

# Create fonts, use Imagefont.truetype

Font=imagefont.truetype (' C:\Windows\Fonts\Arial.ttf ', #字体文件需要有才行)

#获取随机背景颜色和字体颜色

#背景颜色

Def getcolor ():

Return (Random.randint (65,255), Random.randint (65,255), Random.randint (65,255))

#字体颜色

def fontcolor ():

Return (Random.randint (35,127), Random.randint (35,127), Random.randint (35,127))

#将文字写到图像中去

Draw=imagedraw.draw (IM)

For x in range (240):

For Y in range (60):

Draw.point ((x, y), Fill=getcolor ())

For T in range (4):

Draw.text ((* t + ten), GetChar (1), Font=font,fill=fontcolor ())

#保存验证码图像

Im.save (' D:/test.png ')

Note: When running, error code importerror:the _IMAGINGFT C module is not installed error, only need to uninstall PIL, reinstall compiled PIL version can be

Uninstalling Pil:pip Uninstall PIL

Packages that need to be used: import random

Import Image,imagefilter

Import Imagefont

Import Imagedraw
