How I Learned to Code in 4 Months & Got a Job! (No CS Degree, No Bootcamp)

Will AI replace Python coders?

Most Python people agree: AI won't replace developers anytime soon. My thoughts: it will definitely change how we work. If you're using AI without understanding, you'll likely fall behind. If you keep learning and adapt, you'll do fine.

Is 27 too late to start coding?

No, 27 is absolutely not too old to learn programming; many people successfully switch careers into tech at this age or older, proving age is less of a barrier than passion, dedication, and practical skill-building, though you might focus on leveraging existing experience (like data analysis) rather than expecting to become a top-tier software engineer by 30. Employers value what you can do, so build marketable skills, create a strong portfolio, and remember that persistence pays off, even if the learning curve feels steeper at times. 

What is the 80 20 rule in Python?

The 80/20 Rule in Python Codebases

This means that performance optimization should not be applied evenly across the entire codebase. Instead, developers should identify the critical 20 percent of code that consumes most of the runtime and optimize that part first.

Does NASA use C++ or Python?

NASA employs a diverse array of programming languages, including C, C++, Python, Fortran, MATLAB, and Java. This variety underscores the agency's commitment to precision and innovation in space exploration.

Is Python still useful in 2025?

In our Developer Ecosystem Survey 2025, Python ranks as the second most-used programming language in the last 12 months, with 57% of developers reporting that they use it.

Is 2 hours a day enough to learn Python?

Basic Understanding (for general coding knowledge): 1–2 hours a day for 3–6 months. Intermediate Mastery (for simple automation, web scraping, or small projects): 2–3 hours a day for 6–12 months. Advanced Proficiency (for data science, machine learning, or web development): 3–5 hours a day for 12+ months.

Is C++ or Python easier?

If you're just choosing which to learn, it is recommended that you start with Python before trying your hand at using C++, as it's a much more beginner-friendly language that you can easily build on over time.

Did Elon Musk know how to code?

Musk started with a book on the BASIC programming language, a popular language in the 1960s, which many computers still used in the 1980s. The book offered a six-month program to learn to code, but Musk raced through the entire program in three days. It wasn't long before Musk programmed his first video game.

Can I use ChatGPT to learn Python?

Yes, ChatGPT can effectively teach you Python by acting as a personalized tutor, providing explanations, generating code, debugging errors, creating exercises, and even helping with project ideas, but you need to actively engage, verify information (as it can err), and not just copy-paste code to ensure true learning. It's excellent for interactive learning, breaking down complex concepts, and offering customized roadmaps, but always test the code and supplement with documentation for best results. 

Does Elon Musk use Python?

Elon Musk's iconic company, Tesla, operates on an operating system built on the Python programming language. Elon Musk continues to prefer it as his favourite programming language.

Is Google still using Python?

Python is recognized as an official language at Google, it is one of the key languages at Google today, alongside with C++ and Java. Some of the key Python contributors are Googlers and they continue to use, promote, and support the language actively.

Do NASA use Python?

Yes, NASA heavily uses Python for diverse tasks like data analysis, machine learning, automation, scientific computing, and even some mission-critical operations, leveraging its ease of use for tasks from processing Mars rover images to managing James Webb Space Telescope data. While other languages like C/C++ handle flight software, Python excels in ground systems, data pipelines, and scripting due to its extensive libraries and pseudocode-like syntax. 

Is 2 months enough for Python?

Yes, 2 months is enough time to learn Python basics and even some practical skills if you're dedicated (e.g., 2-4 hours daily), but becoming job-ready or mastering advanced concepts takes longer (3-12 months) and requires consistent practice with libraries and projects, not just syntax. You can grasp syntax, loops, and functions quickly, but building real applications or specializing in data science/web development needs more time and practical experience.

Single-responsibility principle (SRP) Open–closed principle (OCP) Liskov substitution principle (LSP) Interface segregation principle (ISP)

Did Joe Biden say "learn to code"?

Yes, Joe Biden famously told coal miners in a 2019 campaign speech in New Hampshire that they could learn to code, saying, "Anybody who can go down 300 to 3,000 feet in a mine, sure in hell can learn to program as well," as part of a larger discussion about transitioning workers to future jobs in a green economy, a comment that drew both criticism and defense. 

Will AI replace coders by 2040?

Research from Oak Ridge National Laboratory maintains there's a high probability of AI replacing software developers by 2040. This aligns with survey data showing 30% of developers expect AI to replace their development work.
