Sample text

Give the square function some other data type, such as a string, and you will receive a TypeError. >>> def square(x): ... return x**2 ... >>> squared_number = square(4) >>> print squared_number 16 Our second function, even_or_odd, is slightly more advanced. This function first checks if it is passed an input that is of type integer. If not, it returns immediately, which causes the function to exit. If it is an integer, it performs some logic and prints if the integer is even or odd. Notice that when we try to give the function the string '5', not to be confused with the integer 5, it returns nothing, whereas in the square function, which lacks any input validation checks, this would have caused an error.

If a > b: ... print str(a) + ' beats ' + str(b) ... >>> [ 25 ] Now For Something Completely Different Notice how when the flow logic evaluates to True then the code indented below the if statement is executed. When it evaluates to False the code is skipped. Typically, when the if statement is False you will have a secondary statement, such as an elif or else to catch other possibilities, such as when "a" is less than or equal to "b". However, it is important to note that we can just use an if statement without any elif or else statements.

However, this quickly becomes more complicated as functions can run without inputs or optional inputs or do not need to return an output at all. Functions are an integral component of any programming language and have already been encountered many times in this chapter. append() is a function that requires input to add to a list. Once a function is created you can invoke it by its name and pass any required inputs. When it comes to writing functions, more is better. It is much easier to handle and troubleshoot a bug in a program with many small functions than one big function.
