random Decimal in python

Question

How do I get a random decimal.Decimal instance? It appears that the random module only returns floats which are a pita to convert to Decimals.

Answer 1

Yet another way to make a random decimal.

import random
round(random.randint(1, 1000) * random.random(), 2)

On this example,

• random.randint() generates random integer in specified range (inclusively),
• random.random() generates random floating point number in the range (0.0, 1.0)
• Finally, round() function will round the multiplication result of the abovementioned values multiplication (something long like 254.71921934351644) to the specified number after the decimal point (in our case we'd get 254.71)
