Ready to move past Excel for complex business analysis? Then you’ll find this course very helpful.

This hands-on introductory Data Science course is aimed at professionals and students who don't have any experience with programming. It will help you advance your career by preparing you to conduct meaningful data analysis in Python on any dataset — large or small.

You’ll begin with the fundamentals of Python, with focus on CSV files in Python, covering concepts like data preprocessing and Exploratory Data Analysis (EDA). In the second half, you'll focus on predictive and inferential analysis using statistical and machine learning techniques, and learn how these techniques can help solve business problems.

Data Science for Non-Programmers

# Operators
**Operators** are used to perform arithmetic and logical operations on data. They use the provided data and give results. Some operators follow the *in-fix* (a **+** b) notation while some follow the *pre-fix* (**-** a) notation.  With **in-fix** notation, the operands are placed on the left and right side of the operator. With **pre-fix** notation, the operator is placed before the operand. We will look at the different kinds of operators in Python in this lesson.


## Arithmetic operators
Arithmetic operators are used to perform arithmetic operations such as addition, multiplication, division, etc. They can be used in conjunction with each other, hence they have an order of *precedence* as well. Some of the most common operators are listed below in order of precedence. 

* `()`: Parenthesis. Whatever is in the parenthesis will be evaluated first.
* `**`: Exponent (**In-fix**)
* `%`,`*`,`/`,`//`: Modulo, Multiplication, Division, Floored Division (**In-fix**)
* `+`,`-`: Addition, Subtraction (**In-fix**)

Let's look at an example. 


This lesson will focus on different types of operators in Python.
