Python är ett tolkat högnivåspråk för allmänna ändamål. Till skillnad från HTML, CSS och JavaScript, som främst används för webbutveckling, är Python mångsidigt och kan användas inom olika områden, inklusive mjukvaruutveckling, datavetenskap och back-end-utveckling. I denna kurs utforskar du de grundläggande aspekterna av Python, och i slutet kommer du att skapa egna funktioner.

Lär dig använda jämförelse- och logiska operatorer, arbeta med villkorsuttryck samt tillämpa medlemskaps- och typjämförelser. Bygg en stark grund i att skriva program som reagerar dynamiskt på olika villkor med hjälp av if/else- och if/elif/else-strukturer.
