Python Essentials

Course Description

The training’s understudies figure out how to program in Python. The course is necessary for understudies new to the language who could conceivably have involvement in other programming dialects. This Python course is shown utilizing Python 3; be that as it may, contrasts between Python 2 and Python 3 are noted. For private Python classes, our educator can concentrate explicitly on Python 2 whenever wanted.

Objectives

After completion of this course, you will learn how to:

• Understand how Python functions and what it's useful for.
• Understand Python's place in the realm of programming dialects.
• Work with and control strings in Python.
• Perform math tasks with Python.
• Work with Python arrangements: records, clusters, word references, and sets.
• Collect client info and yield results.
• Perform stream control preparing in Python.
• Write to and read from records utilizing Python.
• Write works in Python.
• Handle special cases in Python.
• Work with dates and times in Python.

Target Audience

• This course is planned for understudies who need to learn Python. Some programming experience is useful yet not required.

Prerequisites

• This specialization is intended for beginners who would like to master essential programming skills.

Duration

• 5 Days

Course Outline

Module 1: Python Basics

Python, which first appeared in 1991, is one of the most popular programming languages in use. Python is a high-level programming language, meaning that it uses a syntax that is relatively human readable, which gets translated by a Python Interpreter into a language your computer can understand. Examples of other popular high-level programming languages are C#, Objective-C, Java, PHP, and JavaScript. Interestingly, all of these other languages, unlike Python, share a C-like syntax. If you use one or more of those languages, you may find Python's syntax a little strange. But give it a little time. You'll find it's quite programmer friendly.
