Why is wearable technology important?

Assume the variable myWord references a string. Write a statement that uses a slicing

givi [52]

Answer:

"myWord[-5:]"

Explanation:

So whenever you slice a string, the syntax in python is expressed as:

string[a:b:c]

where a=start index (this is included in the sliced string)

b = end index (this is excluded from the sliced string)

c = increment

If any of these are included, they are set to default values, where a=0, b=len(string), and c=1.

The increment isn't necessary here, and it's just so you know the syntax a bit more

Anyways, I'm assuming when the question asks to display "the last 5 characters in the string" it means in order? e.g "abcdefghijk" -> "ghijk" and not "abcdefghijk" -> "kjihg"

The last piece of information to know is what a negative index represents.

For example if I have the piece of code

"

string = "hello world"

print(string[-1])

"

This will output "d", and the negative 1 represents the last letter. If you did -2, it would output the 2nd to last letter and so on.

So to print the last 5 characters, we simply use the -5 as the starting index.

"

string = "hello world"

print(string[-5:])

"

This will print "world" or in other words, the last 5 letters. The reason for this is because the -5 in the first spot means the starting index is the 5th to last letter, and when you have the : after the -5, this is the way of telling python you're slicing the string, and not indexing 1 character. You don't need to include another value after that, because it will default to the last index of the string, or more specifically the last index + 1, since the last index is still included.

So the last thing to know, is that if the string isn't greater than 5 characters, it just prints the entire string, and no errors are raised. You can test this out your self as well. So whenever you have a string that's less than 5 characters the entire string is outputted.

>What is the output of the following code:

ozzi

Answer:

Given code output is "786".

Explanation:

Code:

list1 = [ 'cyber', 786 , 2.23, 'square', 70.2 ]#defining a list list1 that holds value in parameter

print (list1[1] )#use a print method that prints list index value

In the given code a list "list1" is declared that holds value in it and in the next step a print method is declared that prints the first index value of the list.

Question / UJU

DIA [1.3K]

Answer:

Option D: If it is the month of January, then the temperature is cool.

Explanation:

A conditional statement is the one having an if condition in it that says, if the condition is true proceed to the next statement, else not.

Given statements are:

If it is the month of January, then it is winter.

This can be written as: if (January)⇒Winter

If it is winter, then the temperature is cool.

This can be written as: if (winter)⇒ Temperature(cool)

So by combining both the statements, the winter clause will be connected and we get:

if(January)⇒Temperature (cool)

This can be written as:

If it is the month of January, then the temperature is cool.

So, Option D is the correct answer.

i hope it will help you!

How drone technology can impact recreation and entertainment

Maurinko [17]

Drones are become more advanced than ever before. Are now, they are starting to impact recreation. They are small, light, and can maneuver incredibly fast. They are being used in movies, skits, short films, and even high-end videos. Here are some ways drones are changing entertainment:

- Providing high-quality filming, even from 200 feet in the air.

- Reaching spaces where bulky helicopters cannot fit into safely

- Laser shows, where drones shine lights and lasers.

Right now, if you tried to hold your phone still to capture a video, you would not be able to do it. Upon checking the footage, you would see the camera shaking, even if it's just tiny bit. While you can lean it on a surface to fix this, it simply cannot be done in the air to capture. Not to worry, though, you've got drones. They can shoot a steady shot 200 feet in the air. The only thing that could rival drones are expensive, bulky choppers. The drones are cheaper and are mass produced.

However, drones are not only being used to filming movies and films. They are also being used for a different kind of entertainment: Shows. Drones move in formation and shine lights in the night sky, like we saw in the Winter Olympics. They are truly stunning(pics attached).
