There are several ways to present the output of a program; data can be printed in a human-readable form, or written to a file for future use. This chapter will discuss some of the possibilities. 7.1. Python. if index % modulus == 0: print() This code takes the current iteration index and, using the modulo operator, compares it with modulus. If the result equals 0, then it can run interval-specific code. In this case, the function calls print() to add a newline, which starts a new row.

The % symbol in Python is called the Modulo Operator. It returns the remainder of dividing the left hand operand by right hand operand. It's used to get the remainder of a division problem. The modulo operator is considered an arithmetic operation, along with +, -, /, *, **, //. The basic syntax is:Floats and integers are comparable as they are numbers but are usually not equal to each other except when the float is basically the integer but with .0 added to the end. When using ==, if the two items are the same, it will return True. Otherwise, it will return False. You can use = to assign values to variables.In Python, the “//” operator works as a floor division for integer and float arguments. However, the division operator ‘/’ returns always a float value. Note: The “//” operator is used to return the closest integer value which is less than or equal to a specified expression or value. So from the above code, 5//2 returns 2.
