The python try block is part of python exception handling mechanism. The try block is similar to an if-then-else block. If an error occurs the try block stops executing. These errors are known errors for which we have a try block. They are called exceptions. The try block is to notice the error or exception … Read more
In computer programs, some kind of errors are expected. We can simply read those errors and fix the problem. But some errors are bound to happen, usually related to user inputs or mismatch of specific conditions of the program. Since, we know them already and knows that it would occur in some point in time … Read more
In earlier articles about function, we have used parameters and those parameters are replaced with some arguments when a function call takes place.In this article, you will learn about python functions that takes default values or called it named parameters.These named parameters have some values assigned to them. You can always override these default values. … Read more
In the previous articles, you have seen various types of functions. Function either return a value or nothing. In this article, you will learn about functions that return a None. The None is the only value that belong to None Type.When Python Functions Return NoneThere are a number of situations when a python function returns … Read more
While writing a python function and using it in your program, you get lot of errors such typing wrong name of the function, changing the order of definition and function calls, wrong parameters, less parameters(parameter mismatch) and scope errors.Wrong Function Definition and Function Call OrderIn python programming one of the most common error is calling … Read more
Python programming allows function to take some parameters and compute them and return a value. This is very efficient method of programming when it clearly defined what inputs a function will take and what output it returns.Python Program That Compute Sum Of Two MatrixIn this example, we will create two matrix using lists and use … Read more
In the previous example, you have seen that python can take no parameter and return some value. In this example, you will learn that a function can take some parameter and output the results without returning the value.Python Program To Reverse a StringIn this example, we will accept a string as parameter and then reverse … Read more
In this article, you will learn about functions that does not take any parameters, but does return a value. The returned value can be used for further computation.Function That Returns Sum of a List of NumbersIn this example, you will create a list of numbers and then sum the numbers in the list and return … Read more
In the last article, we have seen how a user-defined function is created. The user-defined function has two parts – the function definition and the function call.The function definition may or may not have parameters and it may or may not return a value.In this article, you will see an example of python function with … Read more
So far we have seen many programs which ran sequentially, means executed the lines of codes in a linear manner. We have also seen blocks of code such as if-then-else and loops such as for-loop and while-loop. In this article , you learn about python functions.Once thing is common to all of these codes, that … Read more
