Each tool or software has its pro and its cons, and it always depends on the special kind of problems you try to use a tool for. Generally, it does not harm to know a couple of tools to select the one that is best suited for a particular problem.
What is more relevant to a beginner to choose a (first) programming language is which language is typically used in the field and if there are accessible resources and collegues to get help from.
After knowing one programming language well, you start understanding the programming principles, you start thinking like a programmer, what considerably fascilitates learning another language.
Julia is an excellent solution for challenges related to data analysis and statistical computing. Python is an interpreted language that is not famous for its speed. Self-implemented functions in Python can take a lot longer to compile as compared to Julia or C.
If you already know a language it makes it easier to think as a programmer. In this sense, I recommend that you start with python, which has a steeper learning curve, and then move on to julia.
Both languages Python, Julia, and even R and JavaScript have their pros and cons when it comes to Data Analysis. in some occasions MatLab, SAS and even SPSS have their pros and cons for applications in data analysis. where you can find Excel as the better candidate for some applications of data analysis than all above. therefore when it comes to data analysis it depends on your application or what it is used for.
as example you should consider,
1. application what you are using it for
2. size and complexity of data set
3. the analysis method you are trying to use
4. what domain you are doing the analysis in
5. what are your expected outcomes
6. what are the resources available to you
7. how good are you with programming languages
8. can it done without learning fancy programming language
9. etc.
final thought of mine is, give the main focus what you want to do not what fancy tool you are going to use.
Python is a popular multi-purpose programming language widely used for its flexibility, as well as its extensive collection of libraries, which are valuable for analytics and complex calculations.
Both Python and Julia are popular programming languages for data analysis and scientific computing. They have their own strengths and weaknesses, and the choice between them depends on the specific needs of your project.
One of the main advantages of Python is its large and active community of users, which has led to the development of a wide range of libraries and tools for data analysis and machine learning. Python is also relatively easy to learn and has a readable syntax, which makes it a good choice for beginners.
On the other hand, Julia is a relatively new language that was specifically designed for numerical and scientific computing. It has a number of features that make it faster and more efficient than Python for certain types of tasks, such as linear algebra and optimization. Julia also has a growing ecosystem of libraries and tools for data analysis and machine learning.
In general, Python is a good choice if you are just starting out with data analysis and want a language that is widely used and has a large community of users. Julia is a good choice if you are working on a large-scale data analysis project and need the highest performance possible.
Ultimately, the choice between Python and Julia for data analysis depends on your specific needs and goals. It is worth considering both options and evaluating which one is the best fit for your project
