Embarking on a journey into the world of programming can feel daunting, especially when faced with multiple powerful languages. However, the Udemy course ‘Python, SQL et Powershell pour les (grands) débutants (2025)’ aims to demystify this process, offering a comprehensive learning experience for those with absolutely no prior coding knowledge, as well as developers looking to expand their skillset.
This course truly lives up to its ‘three languages for the price of one’ promise, delivering substantial content across SQL, Python, and PowerShell. The structure is logical and beginner-friendly, breaking down each language into manageable sections.
**Part 1: SQL Deep Dive**
The SQL module is incredibly thorough for beginners. It starts with the essentials: installing SQL Server and Management Studio, creating databases and tables, and performing basic data manipulation (SELECT, INSERT, UPDATE, DELETE). What impressed me was the progression into more advanced T-SQL concepts like LIKE, GROUP BY, BETWEEN, DISTINCT, aggregation functions (MIN, MAX, AVG, COUNT, SUM), string functions (SUBSTRING, FORMAT, CONCAT), and crucially, extensive coverage of joins (INNER, FULL, LEFT, RIGHT, CROSS, OUTER APPLY). The course also delves into date functions, control flow (BEGIN TRY/CATCH, IF/ELSE), ranking functions (ROW_NUMBER, PARTITION BY), conversion functions, and even touches upon stored procedures, views, triggers, and functions. The in-depth exploration of joins and ranking functions is particularly valuable for anyone wanting to truly understand how to query and manipulate data effectively.
**Part 2: Python Fundamentals**
The Python section, built with Python 3.9, is equally robust. It meticulously covers the basics, from installation of Python and VS Code to writing your first scripts. Key concepts like variables, data types, string manipulation, conditional statements (if, else, elseif), logical operators (OR, AND, NOT), lists, tuples, and loops (FOR, WHILE) are explained with clarity. The inclusion of numerous exercises and quizzes ensures that learners actively engage with the material and solidify their understanding.
**Part 3: PowerShell Essentials**
For those new to scripting and automation, the PowerShell module is a fantastic starting point. It introduces cmdlets, creating aliases, comparison operators, and the powerful pipeline concept. You’ll learn to write your first scripts, manipulate objects, understand the `$_` variable, and utilize the PowerShell ISE. The course covers variable declaration, comments, here-strings, constants, conditional statements (IF, ELSEIF, ELSE), the SWITCH command, arrays, and loops (FOR, FOREACH). Creating and using functions, including parameter validation and `Write-Verbose`, is also a key takeaway. The practical exercises here are crucial for grasping PowerShell’s automation capabilities.
**Overall Experience and Recommendation**
With over 12.5 hours of demo content and concise, under-10-minute video lessons, the course avoids being overwhelming or monotonous. The instructor’s focus on practical application and keeping videos engaging is a significant plus. This course is an excellent investment for anyone looking to gain a solid foundation in three highly in-demand languages. It will undoubtedly help you stand out technically, whether among colleagues or in job interviews. If you’re a beginner ready to dive into programming, or a developer looking to broaden your horizons, this course is a highly recommended starting point.
