Good morning. is there a way i can get it to print whatever i put within the sqrt() parenthesis as well. as in;
from math import sqrt
square_root = sqrt(13689)
print " The square root of %d is %d" (whatever is inside sqrt parenthesis, square_root)
such that it prints: the square square root of 13689 is 117
and as such if i change the value inside the parenthesis to say 25 for instance it prints ;
the square root of 25 is 5.

i know i can achieve that by defining the function by myself, but i would also like to know how to do it using a built in or called function. thank you

You can always set the number to be squared as a variable and print that, though I’m sure you’ve realized this already:

from math import sqrt
num = 13689
square_root = sqrt(13689)
print "The square root of %d is %d" % (num, square_root)

Or, without declaring another variable:

from math import sqrt
square_root = sqrt(13689)
print "The square root of %d is %d" % (square_root * square_root, square_root)

Anyone else care to add another method?

Got it. Thank you very much. Have a lovely day.
