Python er et fortolket højniveau programmeringssprog til generelle formål. I modsætning til HTML, CSS og JavaScript, som primært anvendes til webudvikling, er Python alsidigt og kan bruges inden for forskellige områder, herunder softwareudvikling, datavidenskab og back-end udvikling. I dette kursus vil du udforske de centrale aspekter af Python, og ved kursets afslutning vil du kunne udforme dine egne funktioner.

Lær at bruge sammenlignings- og logiske operatorer, arbejde med betingede udtryk samt anvende medlemskabs- og typekontrol. Opbyg et solidt fundament i at skrive programmer, der reagerer dynamisk på forskellige betingelser ved hjælp af if/else- og if/elif/else-strukturer.
