Introduction to Python Programming

Python, med dess många tillämpningsområden, har blivit ett allt mer populärt språk. Under den här kursen lär du dig att skriva och underhålla Python-script.

Du lär dig alla viktiga grunder, som syntax, variabler, datatyper, operatorer och uttryck, loopar, villkorssatser och mycket annat användbart. Kursen innehåller många övningar där du får tillämpa kunskaperna praktiskt.

Målgrupp och förkunskaper

Den här kursen riktar sig till dig som vill komma igång med Python. Kursen är också lämplig för IT-tekniker som vill lära sig Python för att använda det till systemadministration.

 Viss vana av programmering är en fördel.

För att alltid hålla en hög kvalitet på våra teknikkurser använder vi både engelsk- och svensktalande experter som kursledare

Iterables: Sequences, Dictionaries, and Sets

Iterables are objects that can return their members one at a time. The iterables we will cover in this lesson are lists, tuples, ranges, dictionaries, and sets.

Virtual Environments

A virtual environment provides a self-contained directory tree with its own Python installation and additional packages necessary for the project(s) being done in that environment. As such, scripts can be run in a virtual environment that have dependencies that are different from those in other development projects that may be running in the standard environment or in separate virtual environments.

• Packages with pip

Flow Control

This module explains how to change the flow by using conditional statements and loops.

This module explains how to use Python’s built-in modules to work with dates and times.

• Understanding Time
• The time Module
• Time Structures
• Times as Strings
• Time and Formatted Strings
• Pausing Execution with time.sleep()
• The datetime Module
• datetime Objects
• timedelta Objects

File Processing

This module explains how to process files.
