It is not true that learning Python is not advisable. Python is a versatile language that can be used for various applications such as web development, data analysis, machine learning, and more. In fact, Python is one of the most widely used programming languages today, and many companies and industries are adopting it.
Regarding the comments on your Python code, it is important to remember that there will always be people who criticize and try to bring others down. The "import everything" comment is not a constructive criticism and shows a lack of understanding of good programming practices. It is important to only import the modules that are necessary for your program to reduce clutter and improve performance.
The statement that "You're not a programmer if you code in Python" is simply not true. Programming skills are not determined by the language that you use, but rather by your ability to solve problems and develop efficient algorithms. It's important to remember that programming languages are just tools, and the goal is to use the best tool for the job at hand.
