To accomplish this without using a loop,
we can use math on a string.
Example:
print("apple" * 8)
Output:
appleappleappleappleappleappleappleapple
In this example,
the multiplication by 8 actually creates 8 copies of the string.
So that's the type of logic we want to apply to our problem.
<span>def powersOfTwo(number):
if number >= 0:
return print("*" * 2**number)
else:
<span>return
Hmm I can't make indentations in this box,
so it's doesn't format correctly.
Hopefully you get the idea though.
We're taking the string containing an asterisk and copying it 2^(number) times.
Beyond that you will need to call the function below.
Test it with some different values.
powersOfTwo(4) should print 2^4 asterisks: ****************</span></span>
Answer:
The modified program is as follows:
user_input = input()
short_names = list(user_input.split(" "))
short_names.pop(0)
short_names[-1] = "Joe"
print(short_names)
Explanation:
This gets the user input
user_input = input()
This converts input to list
short_names = list(user_input.split(" "))
This removes the first item of the list
short_names.pop(0)
This updates the last item to "Joe"
short_names[-1] = "Joe"
This prints the updated list
print(short_names)
Answer:
the programs and other operating information used by a computer.
Explanation:
<span>In object-oriented approach, functions used to carry out subtasks are also called "helper" functions, because they are usually used by other functions in the object to complete "sub-tasks". Functions are also known as â€methods’. When the task to be carried out by an object is complicated, it is preferable to break it into subtasks or subroutines. It is accomplished by helper functions. They may or may not accept data and may or may not return a value.</span>
