In this example, theis_primefunction checks if a number is prime by testing divisibility from 2 up to the square root of the number. Theprint_primesfunction iterates from 2 to N and prints the prime numbers. I executed the above Python code, and you can see the output in the screensho...
If you don’t, it will fall back to a slightly more explicit string representation made up of a piece of Python code. You’ll learn how to convert fractions to strings later in this tutorial.Rational NumbersWhen you call the Fraction() constructor with two arguments, they must both be ...

The body of the for loop, like the body of the Python while loop, is indented from the rest of the code in the program. Let us take a look at the Python for loop example for better understanding. Python 1 2 3 4 5 6 square = 1 numbers_list = [1,2,3,4,5,6,7] for i ...
