Modify keys/values in dict, use get()

We have seen how to create and access values within a dictionary, so the next step is to look at modifying the values within a dictionary. Remember that to access the values within a dictionary, we use the associated key.

Exercise instructions

Change the price to 132.55.
Change the volume to 70000000
Use the get() keyword to print the new price() value to the console, setting the default argument for get() to Unknown key.

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

apple_stock_data = Dict{String, Float64}("price" => 131.86, "prev_close" => 131.99, "volume" => 55000000)

# Change the price and volume values
apple_stock_data____ = ____
apple_stock_data____ = ____

# Use get() to get the price key in apple_stock_data
println(____(____, ____, ____))

Loops are one of the core concepts that underpin Julia. In this chapter, you'll learn about for loops and while loops, and how to use them to iterate over data structures that you are already familiar with. You will also cover ranges, a useful tool for generating sequences of data.

Exercise 1: For loops Exercise 2: For loops question Exercise 3: Loop over a vector Exercise 4: Loops and enumerate Exercise 5: Looping over nested structures Exercise 6: While loops Exercise 7: Writing a while loop Exercise 8: While loops for iteration Exercise 9: Ranges Exercise 10: Ranges - iteration Exercise 11: Defining ranges Exercise 12: Looping over ranges Exercise 13: Splat unpacking

This chapter focuses on expanding your knowledge of the data structures available in Julia. Learn how to use tuples, dictionaries, multi-dimensional arrays, and structures to store and traverse data quickly and efficiently.

Exercise 1: Tuples Exercise 2: When should you use a tuple?Exercise 3: Create, index, and slice a tuple Exercise 4: Create a NamedTuple for a person Exercise 5: Dictionaries Exercise 6: Create untyped dict, iterate Exercise 7: Create typed dict, iterate Exercise 8: Modify keys/values in dict, use get()

In this chapter, you’ll extend your understanding of functions, exploring positional, keyword, and default function arguments. You will also cover code execution timing, getting a strong understanding of how to measure the time your code takes to run. This chapter will round off with a capstone on writing your own functions to solve real-world problems.

This final chapter will introduce anonymous functions and will recap one of the powerful features of Julia; multiple dispatch. You will learn how to use functions from Python and R packages within Julia and discover how to clean and modify data within dataframes.
