Hour of Python is the project of French and Slovak secondary schools in which students will demonstrate their skills to develop some graphic input by the use of Python programming language commands. The students use these commands in practical activities - to design the project logo and to challenge new friends from foreign school. First kind of challenge is that they code a picture, then they ask foreign partners to write the set of commands for such images. The other kind of challenge will provide the chance to fill in the missing parts of a given code to design the same picture.
