What You Will Learn

  1. Introduction to Python

    35 hours

    In this course, you’ll learn to represent and store data using Python data types and variables, and use conditionals and loops to control the flow of your programs. You’ll harness the power of complex data structures like lists, sets, dictionaries and tuples to store collections of related data. You’ll define and document your own custom functions, write scripts and handle errors. You will also learn to use two powerful Python libraries — Numpy, a scientific computing package, and Pandas, a data manipulation package.

    Prerequisite knowledge

    1. Why Python Programming

      Gain an overview of what you’ll be learning and doing in the course and understand why you should learn programming with Python.

      • Data Types and Operators

        Learn to represent data using Python’s data types: integers, floats, booleans, strings, lists, tuples, sets, dictionaries, compound data structure. Perform computations and create logical statements using Python’s operators: Arithmetic, Assignment, Comparison, Logical, Membership, Identity. You'll also declare, assign, and reassign values using Python variables, modify values using built-in functions and methods, and practice whitespace and style guidelines.

        • Control Flow

          Write conditional expressions using if statements and boolean expressions to add decision making to your Python programs, and learn how to use for and while loops along with useful built-in functions to iterate over and manipulate lists, sets and dictionaries. Condense for loops to create lists efficiently with list comprehensions, and use skip iterations in loops using break and continue.

          • Functions

            Learn to define your own custom functions, create and reference variables using the appropriate scope, and add documentation to functions using docstrings. You'll also define lambda expressions to quickly create anonymous functions and use iterators and generators to create streams of data.

            • Scripting

              Learn to install Python 3 and set up your programming environment, and begin running and editing python scripts. You'll also identify and handle errors and exceptions in your code, open, read and write to files, and find and use modules in Python Standard Library and third-party libraries.

              • Numpy

                Create, access, modify, and sort multidimensional NumPy arrays (ndarrays), and use slicing, boolean indexing, and set operations to select or change subsets of an ndarray. Understand the difference between a view and a copy of ndarray, perform element-wise operations on ndarrays, and use broadcasting to perform operations on ndarrays of different sizes.

                • Pandas

                  Learn to create, access and modify the main objects in Pandas, Series and DataFrames, perform arithmetic operations on Series and DataFrames, load data into a DataFrame, and deal with Not a Number (NaN) values.

                  • Course Project: Explore US Bikeshare Data

                    You will use Python to answer interesting questions about bikeshare trip data collected from three US cities. You will write code to collect the data, compute descriptive statistics and create an interactive experience in the terminal that presents the answers to your questions.
