Python Tutorial

In previous lessons, you learned about different types of loops such as for loop, while loop and for-each loop. Each of the loop terminate successfully. What if you want your loop to exit in between execution, or you want to skip some of the iterations. There are three keywords in python programming that does that … Read more

A python nested loop is loop with in a loop. Python programming allows you to create such loops. Now the choice of loops is totally up to the programmer. You can for-loop inside for-loop, for-loop inside while-loop, while-loop inside a while and so on.Therefore, various combination of loop is possible with deep levels of nesting. … Read more

In the previous article, you learned about the different types of for-loops. The python while-loop can do everything that a for-loop does. However, the for-loop is used when the number of iteration is already known. In this article, we will explore the while loop and know how to use it in out program. While Loop … Read more

In python programming language, thepython for-each loop is another variation of for loop structure. In this loop structure, you get values from a list, set and assign it to a variable during each iteration. It is little hard to understand without an example. Consider the usual way to using for loop. The above construct is … Read more

So far you have learned about different structures of conditional. But the conditionals such as if-then-else also employ different types of logical operators. In this article, you will learn about the conditionals and operators that we can use with conditional structures. There are categories of logical operators that the python programming language uses and they … Read more

The python if-then-else statement runs a block of code based on the condition which can be true or false. Sometimes you need to check multiple conditions event after a block is true. This is achieved using python nested if statements. For example, assume that a user is trying to login to a system. This can … Read more

In previous two articles, we discussed conditional statements such as and . All of those previous structures are using one conditions only, what if, we want to check multiple conditions at different time and make decisions based on the output of those conditions. The python has a special construct to check multiple conditions one after … Read more

In the previous article, you learned about the and how it executes statement if the condition for the is true. But we have not discussed anything about what should happen when is false. The python programming language have a separate block of code to execute when the is false. It is called the . Consider … Read more
