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
Program to check prime number in Python 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...
Integers are whole numbers, but floating-point numbers (called floats in Python) have decimal points. Floats can include a decimal integer exponent after the letter e You can use underscore (_) to separate digits for clarity, as you can for integers you can convert a string containing characte...
Sometimes you can write code to check for errors automatically. For example, if you are computing the average of a list of numbers, you could check that the result is not greater than the largest element in the list or less than the smallest. This is called a “sanity check” because it...
