Using try and except statement for exception handling, using raise to throw out the exception and stop the program.

The print built-in function displays the specified string to the output.

An if else statement is a conditional statement that runs a different set of statements depending on whether an expression is true or false.

Method 1

The def keyword defines a function. A function is a group of statements that can be called upon repeatedly to perform a specific task.

Write a code or draw a flowchart to show the factorised form of a quadratic expression                     ,  or indicate that it cannot be factorised. The input, b, is a positive integer less than 60. 

A variable stores a value that can be referred to or modified later in the program. A name, output, is assigned to the variable as an identifier in this case.

Method 2

The for loop repeats codes within itself for a fixed number of times determined by the specified expression.
