One of the simplest way to check if the User Input is validate is using a Loop. You can use try and except until you get some validate Input:

Each character of a string can be reached with an index number, each string starts with the 0 index. In order to output the part of a string, you have to consider the following: s[startIndex:pastIndex].pastIndex is the length of a string + 1. With the s.replace(„“,“““) operator you can replace parts of a string. You„How to handle Strings“ weiterlesen

Lists and tuples are two data structures in Python that can be used to combine data into one unit. Both data structures allow read access to the individual data. While the data structure list allows a write access, such a write access is not possible with tuples. Lists are data objects that can be changed„Mutable and Immutable“ weiterlesen

In the last article we dealt with recursions and considered the faculty as an example of recursion: It turned out that the use of recursions with a high recursion depth can lead to an impairment of computer performance. One approach to solve this is the bottom-up approach. Instead of recursive programming, a while loop is„Which Repetition?“ weiterlesen

We say these words again and again But they still sound the same to me Say these words again and again And again and again Keane Recursion is a function that calls itself again and again. The standard example is the faculty of the number n. It is the product of all natural numbers less„Again and again“ weiterlesen

… but there need to be one if you are operating with loops in Python. In genereal you have two possibilites: Using a while-loop Using a for-loop A while loop always starts with the word while. Then follows a condition and a colon. Normally, a loop is only terminated if the condition in the loop„There is no end…“ weiterlesen

… you will know how to use conditionals in Python. ‚If-Sentences‘ are not only important in the English language but also in the computer language. With them it is possible to print conditions. Using the following example, which checks whether the given pages are a triangle, I would like to explain the use of ‚if‘„If you read this blog post…“ weiterlesen

If a program is too long, it may be useful to split it into several files. If you have definied functions, it is also useful to be able to use them in several programs. A module is a file which is defined in one file and can be reused in another file and which contains„Modules“ weiterlesen

User-defined functions are reusable code blocks. They only need to be written once, then they can be used multiple times. They can even be used in other applications, too. In Python a function is defined using the def Keyword.To call a function, use the function name(): With the Return command, you can return values of„The Function of a Function is to Function“ weiterlesen
