This course introduces the dictionary data structure and user-defined functions. You’ll learn about local and global variables optional and keyword parameter-passing named functions and lambda expressions. You’ll also learn about Python’s sorted function and how to control the order in which it sorts by passing in another function as an input. For your final project you’ll read in simulated social media data from a file compute sentiment scores and write out .csv files. It covers chapters 10-16 of the textbook
“Fundamentals of Python Programming” which is the accompanying text (optional and free) for this course.
The course is well-suited for you if you have already taken the Python Basics course and want to gain further fundamental knowledge of the Python language. Together both courses are geared towards newcomers to Python programming those who need a refresher on Python basics or those who may have had some exposure to Python programming but want a more in-depth exposition and vocabulary for describing and reasoning about programs.
This is a follow-up to the Python Basics course (course 1 of the Python 3 Programming Specialization) and it is the second of five courses in the specialization.
WEEK 1

Files and CSV Output
In week one the video lectures and the Runestone textbook will introduce you to the idea of incorporating files into your programs as an additional source of data. You will learn how to read from a file write to a file and how to work with the .csv data format.

Dictionaries and Dictionary Accumulation
In week two the video lectures and the Runestone textbook will focus on a new data type dictionaries. You will be introduced to the mechanics of dictionaries and then get practice using them in accumulation patterns both to build a dictionary using the pattern as well as find the best or worst result using the pattern.

Functions and Tuples
In week three you will be introduced to the construction of functions. Up to this point you have used functions in the programs before but have not had a chance to write your own functions including how to define a function how to incorporate parameters how to return data from a function the local or global scope of variables and potential side effects that could occur from function execution. Finally we look at tuples more in depth and how automatic packing and unpacking of tuples can be used in functions and in for loops.

More Iteration and Advanced Functions
In week four the video lectures and the Runestone textbook will outline a more advanced iteration mechanism the while loop. You will be introduced to using it when getting feedback from users as well as applying it to the turtle module to draw images. Additionally you will also be exposed to more advanced function concepts such as the idea of parameters being optional not required and anonymous functions using lambda.

Sorting
In week five the videos and Runestone textbook will detail how to sort python objects - both the basics and more advanced forms of sorting for dictionaries and how to break a tie (if that occurs). The final course assessment will be a project that asks you to read fake auto-generated data from a social media site to analyze social media post sentiments. You will submit a csv file as well as images of graphs that demonstrate your findings.
