We also compare Python and R in solving business problems for actual companies. We give some examples of how to utilize both Python and R. For example, we provide examples of teaching correlation coefficient both with Python and R. We provide three teaching goals for Python and R: 1, helping students to find a job; 2, students receive higher salary; 3, low cost for learning packages both for Python and R. Keywords: Big data, Teaching R, Teaching Python, demonstrations, examples of teaching R and python, Python Python, easy to learn, is a general-purpose programming language. It has a mature and growing ecosystem of open-source tools for mathematics and data analysis for statistics and analytics, which is becoming the language of choice for scientists and researchers. Python code can be written like programing language. The main focus is to execute an entire series of instructions at once, it can also be executed line by line or block by block, making it unique and suitable for working with data interactively. Students learned a bit of programming and problem solving which were relegated to advanced courses. In addition to object-oriented programming as the dominant paradigm. It has led textbook authors to bring powerful, industrial-strength programming languages such as C++ and Java into the introductory software curriculum. As a result, instead of experiencing the rewards and excitement of solving problems with computers, beginning computer science students become overwhelmed by the combined tasks of mastering advanced concepts and the syntax of a programming language. This research will use the Python programming language as a way of making the course in mathematic more manageable for students and instructors alike for undergraduate education. • Python has simple, conventional syntax with its statements. The expressions are created with conventional notation found in algebra. Thus, one can spend less time dealing with the syntax of a programming language and more time to solve problems. 1 • It is easy for beginners to write simple programs in Python such as support for object- oriented software development. • Python is interactive. Users can enter expressions and statements to try out experimental code and receive immediate feedback. • Python is free and is in widespread use in the industry. Students can download Python to run on a variety of devices Based on more than 1000 developers, in figure 1 it can be see that 61% of the developers use Python as their primary programing language. Figure 1 shows the most popularly used software language platform by our respondents. As seen in the figure below Python and R are the most heavily used platform by our respondents. The usage of Python and R are only 17% apart from each other, and Python is the leader. Figure 1: Share of Python, R, Both, or Other platforms usage for Analytics, Data Science, Machine Learning, 90% 80% 76% 70% 60% 59% 54% 50% 40% 30% 20% 10% 18% 17% 9% 6% 5% 2% 0% 2 Table 1 Python 7955 6073 R 7955 4708 SQL 7955 4261 Java 7955 1453 Hadoop/Hive/Pig 7955 1378 SAS Base 7955 738 IBM SPSS 7955 472 Statistics Amazon 7955 425 Machine Learning Minitab 7955 150 Based on more than 1000 developers, in figure 1 it can be see that 61% of the developers use Python as their primary programing language. (Python Developers Survey 2016: Findings) Figure 2: Use of Python in the Software Development There are about 46% of developers use python programing language as their Data analysis tool instead of traditional programmers or Web developers. Use of Python in the Software Development Other 14% Web Development 22% Software Development 18% Data analysis 19% Scientific or Data Analysis 27% (Python Developers Survey 2016: Findings) 3 R R is an open source software which designed to run statistical analyses which makes the software highly appealing, as it is able to keep up with the demands of a growing number of varied business structures. One of the core benefits of teaching R to students is that it is a highly standardized programming language (Economist 662f, 2014). This means that students need not worry about highly variable language structures or deep understanding of the different languages with which one
