The code for this article is available onGitHub Theabs()function returns the absolute value of a number. In other words, if the number is positive, the number is returned, and if the number is negative, the negation of the number is returned. main.py print(abs(-21))# 👉️ 21print...
Int, or integer, is a whole number, positive or negative, without decimals, of unlimited length. Example Integers: x =1 y =35656222554887711 z =-3255522 print(type(x)) print(type(y)) print(type(z)) Try it Yourself » Float
These methods will test a given unit of code using different inputs and check for the expected results.Here’s a quick test case that tests the built-in abs() function:Python import unittest class TestAbsFunction(unittest.TestCase): def test_positive_number(self): self.assertEqual(abs(10...

Optional argument whence defaults to 0 (offset from start of file, offset should be >= 0); other values are 1 (move relative to current position, positive or negative), and 2 (move relative to end of file, usually negative, although many platforms allow seeking beyond the end of a file...
A prime number is a whole number greater than 1 that has no positive divisors other than 1 and itself. The first few prime numbers are {2, 3, 5, 7, 11, ….}. n = 7 if n>1: for i in range(2, int(n/2)=1): if(n%i)==0: print(n,“ is not a prime number”) break...
