Get cushion's color. Assign it to the variable col_cushion.

col_cushion = cushion.color

col_cushion `= `cushion`.`color

Get the value of qty. Assign it to the variable on_hand.

sku_1212 = Product("premium", 144, "instock")

on_hand = sku_1212.qty

In a single line of code display the value of an attribute for an instance. Make everything up.

print(patient0376.condition)

^ *print$[a-zA-Z_][a-zA-Z0-9_]*\.[a-zA-Z_][a-zA-Z0-9_]*$ *$

Assign the value of an attribute of an instance to a list element. Make everything up.

city_pops[16] = bangkok.population

^ *[a-zA-Z_][a-zA-Z0-9_]*\[-?[0-9]+\] = [a-zA-Z_][a-zA-Z0-9_]*\.[a-zA-Z_][a-zA-Z0-9_]* *$

Assign the value of an attribute of an instance to a dictionary item. The dictionary key is a string. Make everything up.

australian_cities["capital"] = australia.capital

^ *[a-zA-Z_][a-zA-Z0-9_]*\[•.+•\] = [a-zA-Z_][a-zA-Z0-9_]*\.[a-zA-Z_][a-zA-Z0-9_]* *$

If an attribute value of an instance equals another attribute value of that same instance, display a message. Make everything up.

if xyz.first_name == xyz.last_name:
print("Weird!")

^ *if ([a-zA-Z_][a-zA-Z0-9_]*)\.[a-zA-Z_][a-zA-Z0-9_]* == \1\.[a-zA-Z_][a-zA-Z0-9_]*:\n print$•.+•$ *$

An instance of this class has been created. Assign the value of one of its attributes to a variable. Make everything up, including the name of the instance.

def __init__(self, size, color, fabric):

material = sku2020.fabric

^ *[a-zA-Z_][a-zA-Z0-9_]* = [a-zA-Z_][a-zA-Z0-9_]*\.(size|color|fabric) *$

Code a class that has just one attribute, an integer. Code an instance of the class. Then display the value of the instance's attribute. Make everything up.

class Student():
def __init__(self, age):
self.age = age
id4044 = Student(19)
print(id4044.age)

^ *class ([A-Z][a-zA-Z0-9_]*):\n def __init__$self, ([a-zA-Z_][a-zA-Z0-9_]*)$:\n self\.\2 = \2\n([a-zA-Z_][a-zA-Z0-9_]*) = \1$[0-9]+$\nprint$\3\.\2$ *$

Code an instance of this class.
Display the value of one of its attributes.
Click the Run button above your code. If you've coded correctly, the value will display in the right-hand panel. (You can click Instructions at the top of the right-hand panel to see the correct code.)
