Which of the following is/are true of the print
function?
You’ve seen the len function a couple times now.
Describe its behavior in terms of its inputs, effects,
and return value.
Which of the following programs will not cause an error when run?
def greet():
print("Hi there!")
greet() def greet():
print("Hi there!") greet()
def greet():
print("Hi there!") def greet:
print("Hi there!")
greet()Consider the following program:
def h2m(hours, minutes):
total_mins = 60 * hours + minutes
return total_mins
arg1 = int(sys.argv[1])
arg2 = int(sys.argv[2])
print(h2m(arg1, arg2))80. If the first command line argument was
1, what must the second one have been?80. If you don’t know anything about either command
line argument, how many possible pairs of numbers could have been given
as command line arguments?Consider the following program:
def pnmr(n, r):
print(n % r, end=" ")
size = 7
rad = 3
for num in range(0,size):
pnmr(num, rad)Write a function parrot that takes one string
argument (s) and one integer argument (n) and
prints that string n times with a space in between; at the
end, the function should print a single newline. Examples:
>>> parrot("hello!", 3)
hello! hello! hello!
>>> parrot("click", 5)
click click click click click
>>>Write a function rectangle_area that takes two
numbers height and width and
returns the area of a
height-by-width rectangle. Recall that a \(h \times w\) rectangle has area \(h*w\).
Write a function circle_area that takes one number
radius and returns the area of a circle
with that radius. Recall that a circle with radius \(r\) has area \(\pi r^2\).
Write a function get_float that takes a string,
prints that string, then prompts a user for a floating-point number and
returns their input converted to a float.
>>> get_float("Enter a radius: ")
Enter a radius: 4
4.0(Note: in the above, 4 is entered by the user, and
4.0 is printed on the Thonny shell in dark blue, showing
the return value of the call to get_float)
Use the functions from the prior three problems to create a geometry game as follows. The program takes two command line arguments specifying the width and height of a rectangle. Then, it repeatedly prompts the user for a radius. For each radius provided, print a message saying whether the circle with the given radius has area greater than, smaller than, or equal to the rectangle’s. If the user enters a negative number, the program should terminate.
Write a function print_banner that takes a string
argument and prints that string, surrounded by a rectangle of
# symbols. Here are some examples of how the function might
be called:
>>> print_banner("Hello!")
########
#Hello!#
########
>>> print_banner("You enter a room with two doors on the opposite wall.")
#######################################################
#You enter a room with two doors on the opposite wall.#
#######################################################
>>>Assume there are no newline characters (\n) in the
string you’re given, and that the string can be printed on one
line.
Write a function add_banner function that does the
same thing as print_banner, except that it
returns the string as a banner instead of
printing it.
Note: It came to my attention that you don’t have the tools you need to solve this one! After Week 6 you will, but don’t worry if you aren’t able to solve this yet.
Modify your add_banner function to implement text
wrapping, so that a string longer than 80 characters will be broken into
multiple lines. You can still assume the string does not contain any
newlines. An example might look something like the following:
>>> print_banner("Modify your print_banner to implement text wrapping so that a string longer than 80 characters will be broken into multiple lines.")

#Modify your print_banner to implement text wrapping so that a string longer than#
#80 characters will be broken into multiple lines. #
