A menu bar organizes related commands together, under a tab.
So the answer is <span>b. menu bar</span>
Answer:
Answer is b. 10
Explanation:
The find() method is used to search the string for a specified value and searches the first occurrence of that value. It returns the position of that specified value. If the value is not found, this method returns -1.
Lets say we have a message variable that contains the string Happy holidays.
message = "Happy holidays"
We use the method find() to find days word from the Happy holidays string in the message variable.
The find() method will find the position of day.
If we look at the string Happy holidays we see that the word day is at the 10th position of the string.
H 1
a 2
p 3
p 4
y 5
h 6
o 7
l 8
i 9
d 10
a 11
y 12
s 13
So it is at 10th position so the statement
message.find("days")
returns 10
Different video files and operating system versions can cause compatibility issues to arise between computer systems.
Since, file formats and operating systems may not be compatible with each other. For example, earlier versions of Windows may not be able to play certain types of video files due to the codecs used to encode them.
<h3>Importance of compatibility between operating system computer systems</h3>
Compatibility between operating systems is important because it allows different computer systems to interact and share resources. This includes sharing of programs, files, and data.
Compatibility also allows users to access applications and services on different platforms. It also enables efficient use of hardware and software resources, as well as efficient use of resources in a network. Compatibility also ensures that computer systems can communicate with each other and can access the same resources. Without compatibility, it would be difficult for computer systems to interact with each other.

Answer:
def select_short_strings(string_list):
new_list = []
for s in string_list:
if len(s) < 20:
new_list.append(s)
return new_list
lst = ["apple", "I am learning Python and it is fun!", "I love programming, it is easy", "orange"]
print(select_short_strings(lst))
Explanation:
- Create a function called <em>select_short_strings</em> that takes one argument <em>string_list</em>
Inside the function:
- Initialize an empty list to hold the strings that are less than 20
- Inside the loop, check the strings inside <em>string_list</em> has a length that is smaller than 20. If found one, put it to the <em>new_list</em>.
- When the loop is done, return the <em>new_list</em>
- Create a list to check and call the function
