I wrote a sample form page with a simple math problem to solve -- 2 or
3 random small integers to add and put the result in a form field
def produce_expression():
"""
return a tuple: expression (str), answer (int)
"""
num_terms = random.randint(2,3)
operands = []
while num_terms:
n = random.randint(1,21)
operands.append(n)
num_terms -= 1
result = sum(operands)
string_operands = map(str, operands)
expression = " + ".join(string_operands)
return expression, result
Its not as annoying as captcha and I think it would work with audio
browsers. Never tested
