image = ImageCaptcha(width = 280, height = 90)

captcha_text = 'python'

data = image.generate(captcha_text)

image.write(captcha_text,'CAPTCHA.png')

Program to find minimum cost path

R = 3

C = 3

def minCost(cost, m, n):

tc = [[0 for x in range(C)] for x in range(R)]

tc[0][0] = cost[0][0]

for i in range(1, m + 1):

tc[i][0] = tc[i-1][0] + cost[i][0]

for j in range(1, n + 1):

tc[0][j] = tc[0][j-1] + cost[0][j]

for i in range(1, m + 1):

for j in range(1, n + 1):

tc[i][j] = min(tc[i-1][j-1], tc[i-1][j],tc[i][j-1]) + cost[i][j]

return tc[m][n]

cost = [[1, 2, 3],

[4, 8, 2],

[1, 5, 3]]

print(minCost(cost, 2, 2))
