A Smarter Way to Learn Python - Chapter 43 Exercises

When you use positional arguments in a function call, the order of the arguments has to match the order of the ________s in the function.

parameter

^ *parameter[s]? *$

When you use keyword arguments in a function call, the function's parameters match all the _________ in the function call, not the order of the arguments.

keys

^ *key[s]? *$

The function call has two arguments. The key in the second argument is second_pet, and the value is "dog". Complete the code.

compare(first_pet = "cat"_________________

, second_pet = "dog")

, `second_pet `= `"`dog`"`)

Call the function named calc. The arguments are x, which is 23, and y, which is .4 (that's point 4)

calc(x = 23, y = .4)

Code the first line of the function that this code is calling.

analyze(nation = "Bangladesh", pop = 163000000)

def analyze(nation, pop):

def analyze$(nation, pop|pop, nation)$:

Code the first line of a function with one keyword parameter. Then code the function call. The value paired with the key is "Homer". Make up the function name and the key.

def silly_function(character):
silly_function(character = "Homer")

^ *def ([a-zA-Z_][a-zA-Z0-9_]*)$([a-zA-Z_][a-zA-Z0-9_]*)$:\n\1$\2 = •Homer•$ *$

Call this function using keyword arguments. Make up the values, which are strings.

def say_hi(greeting, name):
print(greeting + ", " + name)

say_hi(greeting = "Yo", name = "Rocky")

^ *say_hi$greeting = •.+•, name = •.+•$ *$

Code a function call with two keyword arguments. Use the following variables, not the literal numbers, to represent the values. Make up the function name and the keys.

base = 100
percentage = .015

calc(first_arg = base, second_arg = percentage)

^ *[a-zA-Z_][a-zA-Z0-9_]*$[a-zA-Z_][a-zA-Z0-9_]* = base, [a-zA-Z_][a-zA-Z0-9_]* = percentage$ *$

Code a function call with three keyword arguments. The first value is a string. The second value is an integer. The third value is the name of a dictionary. Make everything up.

process_stuff(text = "Result: ", qty = 144, dict = products)

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

Code a function call with a single keyword argument. Use the following variable as the value. Make up the function name and the key.

best_guess = -10.3 % 1.98

calc(num = best_guess)

^ *[a-zA-Z_][a-zA-Z0-9_]*$[a-zA-Z_][a-zA-Z0-9_]* = best_guess$ *$

Code a function that has two keyword parameters, first_name and last_name. The function displays the concatenation of first_name plus a string that's just a space plus last_name.
Call the function, assigning your first and last names to the keywords.

Begin by coding the function call on line 12. It has three keyword arguments. The values are the name of the dictionary, the name of one of the lists in the dictionary, and the index number of an element in the list. The function name and the keys are your choice.
Code the function starting on line 4. It targets the element within the list within the dictionary. Then it displays the targeted name.
Click the Run button above your code. If you've coded correctly, a name from one of the lists will display in the right-hand panel. (You can click Instructions at the top of the right-hand panel to see the correct code.)
