y = 0.00000020
z = 1000

a = 0.000000100

Answer 1

Based on python documents you can use getcontext()

it will be like this:

from decimal import getcontext

#Here you set decimal numbers limit(in your case 10 digits):
getcontext().prec = 10

You could do something like

print '{0:.10f}'.format(variable)

Where the 10f is the digits you want to go and variable is what you want to print
