    Coding or programming is important skill of 21st century. Block-based languages, such as Scratch, are becoming more and more popular tools for initial programming instruction, because they are simple to learn and teach. They can highly motivate students because of their colorfulness, symbols, visual elements and simplicity. Although, many didactics of computer science think, that students should move on to a text-based programming language such as Python, once they have mastered visual programming languages. Modern didactic of computer science tends to teach students how to transfer the programming and thinking skills, learnt while using Scratch, to Python. Expert programmers and didactics of computer science consider that programming in higher programming languages allows more freedom of expression. These languages are usually textual such as Python. In the diploma thesis we are concerned with different points of view form didactics of computer science or experts in the field of programming regarding the transition from block based to text based programming. The opinion among them is that the transition is necessary; most of them also agree that to make things easier we can use graphical editors such as Blockly. In Blockly students stack blocks just like in Scratch, but on the side bar, there is Python (or JavaScript) code displaying. This way students see the code; they can read and explain it with teacher's help. In the research we were interested in the view of primary school teachers and high school teachers if the transition from block based to text based programming is needed and reasons why.
