Question

Please code in Python:

A function can be assigned to a variable and passed into another function as an argument. Consider the following function that executes a function twice:

def exec_2(f):
    f()
    f()

any function that is passed into exec_2() will be executed twice without parameters. Your task is to write a function exec_4(f) that takes in a function f as a parameter and executes the function f 4 times using the function exec_2. The function f in this case will draw a cute koala bear, and, in conjunction with, exec_4(), you will draw 4 koalas on the same tree! Suppress the newline in the print statement for the koala, this can be done using print's end argument.

Default template code:

koala = """
             |       :     . |
             | ' :      '   |
             | . |   ' | |
   .--._ _...:.._ _.--. , ' |
( , `        ` , )   . |
   '-/              \-' |   |
     | o   /\   o |       :|
     \     _\/_     / : '   |
     /'._   ^^   _.;___      |
   /`    `""""""`      `\=   |
/`                     /= .|
;             '--,-----'=    |
|                 `\ |    . |
\                   \___ :   |
/'.                     `\= |
\_/`--......_            /= |
            |`-.        /= : |
            | : `-.__ /` .   |
            |    .   ` |    '|
            | . : `   . | |"""

def exec_2(f):
    f()
    f()

def exec_4(f):
    # define this function using exec_2
  
# define a new function here that prints out the koala once

# use your function and exec_4 to draw 4 koala bears!

Answer 1

Here is the python code to print 4 koala bears by calling the functions.

There are sufficient comments in the code for you to understand.

Note: You may look the screenshot of the code to have better understanding of the indentation.

Python code:

#function to print koala bear once
def f():
koala = """
| : . |
| ' : ' |
| . | ' | |
.--._ _...:.._ _.--. , ' |
( , ` ` , ) . |
'-/ \-' | |
| o /\ o | :|
\ _\/_ / : ' |
/'._ ^^ _.;___ |
/` `""""""` `\= |
/` /= .|
; '--,-----'= |
| `\ | . |
\ \___ : |
/'. `\= |
\_/`--......_ /= |
|`-. /= : |
| : `-.__ /` . |
| . ` | '|
| . : ` . | |"""
#print koala variable
print(koala, end='')
  
#function to print twice koala
def exec_2():
#call function f() twice
f()
f()
  
#function to print koala 4 times
def exec_4():
#call function exec_2() twice
exec_2()
exec_2()
  
#call function exec_4() to print bear 4 times
exec_4()

Output:
