start course for free what you ll learn assess methods for loading and processing large or streaming datasets using pandas chunksize and custom generator functions define the sequential steps required to aggregate data extracted from iterators comprehensions or generators into meaningful summary statistics differentiate scenarios in which list comprehensions generator expressions or iterator based chunk processing provide optimal memory efficiency identify the characteristics and behaviors of python iterables and iterators within the for loop execution model recognize the correct syntax and resulting structures of list comprehensions dictionary comprehensions and generator expressions prerequisites introduction to functions in python 1 using iterators in pythonland you ll learn all about iterators and iterables which you have already worked with when writing for loops you ll learn some handy functions that will allow you to effectively work with iterators and you ll finish the chapter with a use case that is pertinent to the world of data science and dealing with large amounts of data in this case data from twitter that you will load in chunks using iterators introduction to iterators 50 xp iterators vs iterables 50 xp iterating over iterables 1 100 xp iterating over iterables 2 100 xp iterators as function arguments 100 xp playing with iterators 50 xp using enumerate 100

twitter data 100 xp congratulations 50 xp view details start chapter 2 list comprehensions and generators in this chapter you ll build on your knowledge of iterators and be introduced to list comprehensions which allow you to create complicated lists and lists of lists in one line of code list comprehensions can dramatically simplify your code and make it more efficient and will become a vital part of your python toolbox you ll then learn about generators which are extremely helpful when working with large sequences of data that you may not want to store in memory but instead generate on the fly list comprehensions 50 xp write a basic list comprehension 50 xp list comprehension over iterables 50 xp writing list comprehensions 100 xp nested list comprehensions 100 xp advanced
