A Smarter Way to Learn Python - Chapter 75 Exercises

Save this dictionary to a JSON file. (2 lines of code) Assume the json module has already been imported. Make up the filename and file handle.

bird_dict = {
  "crow": "corvid",
  "robin": "thrush",
  "owl": "raptor",
}

with open("bird_file.json", "w") as j:
json.dump(bird_dict, j)

^ *with open$•.+•, •w•$ as ([a-zA-Z_][a-zA-Z0-9_]*):\n json\.dump$bird_dict, \1$ *$

Open a JSON file for reading. Make everything up.

with open("bird_file.json") as j:

^ *with open$•.+•$ as [a-zA-Z_][a-zA-Z0-9_]*: *$

Fill in the blank.

with open("customer_29876.json") as f: customer_29876 = ____________

json.load(f)

json`.`load`(`f`)

Code the next line. Assign the content to owl_dict. Start by indenting.

with open("owls.json") as file_to_read:

owl_dict = json.load(file_to_read)

Code the next line. Make up the variable. Remember to indent.

with open("owls.json") as j:

owls_dict = json.load(j)

^ * [a-zA-Z_][a-zA-Z0-9_]* = json\.load$j$ *$

Read the file and assign its content to a variable. Then print the content. Indent your first line, but not your second line. Make up the name of the variable.

with open("products.json") as f:

dict = json.load(f)
print(dict)

^ * ([a-zA-Z_][a-zA-Z0-9_]*) = json\.load$f$\nprint$\1$ *$

Open a JSON file for reading, then read it. Make everything up.

with open("team_list.json") as j:
teams = json.load(j)

^ *with open$•.+\.json•$ as ([a-zA-Z_][a-zA-Z0-9_]*):\n [a-zA-Z_][a-zA-Z0-9_]* = json\.load$\1$ *$

A dictionary has been assigned to the variable products. Save it in a JSON file. Then open the file and read it. Assume that the json module has already been imported. Make up whatever you need to make up.

with open("prods.json", "w") as j:
json.dump(products, j)
with open("prods.json") as j:
p_dict = json.load(j)

^ *with open$•(.+)\.json•, •w•$ as ([a-zA-Z_][a-zA-Z0-9_]*):\n json\.dump$products, \2$\nwith open$•\1\.json•$ as ([a-zA-Z_][a-zA-Z0-9_]*):\n [a-zA-Z_][a-zA-Z0-9_]* = json\.load$\3$ *$

Open and read a JSON file containing a list. Assign one of the list elements to a variable. Don't indent the line that assigns the list element. Make everything up.

with open("genius_list.json") as j:
the_list = json.load(j)
third_genius = the_list[2]

^ *with open$•.+\.json•$ as ([a-zA-Z_][a-zA-Z0-9_]*):\n ([a-zA-Z_][a-zA-Z0-9_]*) = json\.load$\1$\n[a-zA-Z_][a-zA-Z0-9_]* = \2\[-?[0-9]+\] *$

Open and read a JSON file containing a dictionary. Assign one of the values to a variable. The key is a string. Don't indent the line that assigns the dictionary value. Make everything up.

with open("animal_sounds.json") as j:
sounds = json.load(j)
cat_sound = sounds["cat"]

^ *with open$•.+\.json•$ as ([a-zA-Z_][a-zA-Z0-9_]*):\n ([a-zA-Z_][a-zA-Z0-9_]*) = json\.load$\1$\n[a-zA-Z_][a-zA-Z0-9_]* = \2\[•.+•\] *$

In IDLE code a Python program that imports the json module...
...reads the JSON file containing a list that you coded in the last chapter...
...and displays the list.
Save the Python program to the Desktop and run it.
Open the JSON file in IDLE.
