I think the correct answer would be that it facilitates the transport of data. It is a very useful tool in the transport and storage of data. XML, also, uses human language rather than computer language so it can be used easily by new users.

#Write a function called string_finder. string_finder should #take two parameters: a target string and a search string. #The fun

adoni [48]

Answer:

I am writing a Python program:

def string_finder(target,search): #function that takes two parameters i.e. target string and a search string

position=(target.find(search))# returns lowest index of search if it is found in target string

if position==0: # if value of position is 0 means lowers index

return "Beginning" #the search string in the beginning of target string

elif position== len(target) - len(search): #if position is equal to the difference between lengths of the target and search strings

return "End" # returns end

elif position > 0 and position < len(target) -1: #if value of position is greater than 0 and it is less than length of target -1

return "Middle" #returns middle

else: #if none of above conditions is true return not found

return "not found"

#you can add an elif condition instead of else for not found condition as:

#elif position==-1

#returns "not found"

#tests the data for the following cases

print(string_finder("Georgia Tech", "Georgia"))

print(string_finder("Georgia Tech", "gia"))

print(string_finder("Georgia Tech", "Tech"))

print(string_finder("Georgia Tech", "Idaho"))

Explanation:

The program can also be written in by using string methods.

def string_finder(target,search): #method definition that takes target string and string to be searched

if target.startswith(search): #startswith() method scans the target string and checks if the (substring) search is present at the start of target string

return "Beginning" #if above condition it true return Beginning

elif target.endswith(search): #endswith() method scans the target string and checks if the (substring) search is present at the end of target string

return "End" #if above elif condition it true return End

elif target.find(search) != -1: #find method returns -1 if the search string is not in target string so if find method does not return -1 then it means that the search string is within the target string and two above conditions evaluated to false so search string must be in the middle of target string

return "Middle" #if above elif condition it true return End

else: #if none of the above conditions is true then returns Not Found

return "Not Found"

What advantage do ExpressCard modules and USB adapters offer over expansion cards?

ss7ja [257]

<span>ExpressCard modules and USB adapters are faster and smaller. They are easier to plug into a computer and allow a person to add memory, wired and wireless communications, multimedia, and security features by inserting the small card or adapter into a small slot in the computer.</span>

Charlie has a large book collection. He was keeping track of it in a spreadsheet, but it has grown big enough that he wants to c

zepelin [54]

Answer:

Check the explanation

Explanation:

Ans 1) storing the data in one single row comes with its own barriers and that is if you delete one of the record in the spreadsheet, all the equivalent records which you didn't wanted to delete would be deleted. For take for instance, if you wish to delete the record of author "James Taylor" then all the books he has written would also be deleted from the spreadsheet.

Ans 2) In 1NF, all row is expected to have only 1 tuple, but here in this spreadsheet the title field for Author "James Taylor" has 2 books, so it would be separated into single rows.

Ans 3) The table in the attached image below doesn't delete with Delete anomaly, i.e., for author "May Norton" if you delete this record, then the only book written by her would be deleted.

So, you have to convert this table into 2NF.

Make separate tables for Author and Book

Author(Author Name, Author Country)

Books(Author Name, Book title, Publisher, Publisher Location, Year, price)

This cannot be normalized any further.

Taylor and Rory are hosting a party. They sent out invitations, and each one collected responses into dictionaries, with names o

disa [49]

Answer:

Following are the code to this question:

def combine_guest(guest1, guest2):#defining a method combine_guest that accepts two dictionary

guest2.update (guest1)#use dictionary guest2 that use update method to update guest2 dictionary

return guest2#return guest2 dictionary values

Rory_guest= { "Ada":2, "Ben":3, "Dav":1, "Jo":3, "Charry":2, "Terry":1, "bob":4}#defining a dictionary and add value

Taylor_guest = { "Dav":4, "Nan":1, "bobert":2, "Ada":1, "Samantha":3, "Chr":5}#defining a dictionary and add value

print(combine_guest(Rory_guest,Taylor_guest))#calling the combine_guest method

Output:

{'Nan': 1, 'Samantha': 3, 'Ada': 2, 'bob': 4, 'Terry': 1, 'Jo': 3, 'Ben': 3, 'Dav': 1, 'Charry': 2, 'bobert': 2, 'Chr': 5}

Explanation:

In the code a method, "combine_guest" is defined, that accepts two dictionaries "guest1, guest2" inside the method, in which the "guest2" dictionary uses the update method to combine the value of the guest1 dictionary and use a return keyword to return guest2 values.

In the next step, two dictionaries are declared, that holds some values and use a print method to call the "combine_guest" method and prints its return values.

A company is performing an analysis on the computers at its main office. The computers are spaced along a single row. The analys

harina [27]

Answer:

array = input("Enter the list of computer memory: ").split(',')

int_arr = [int(x) for x in array]

segment = int(input("Enter the length of segment to analyze: "))

list_len = len(int_arr)

segList = []

mini = []

for x,i in enumerate(int_arr):

seg = int_arr[i-1:segment+i-1]

if len(seg) == segment:

segList.append(seg)

for x in segList:

mini.append(min(x))

result = mini.index(min(mini))

print("Segment with the minimum memory is: ",segList[result])

Explanation:

The python program prints out the segment after analysis, with the smallest disk memory space. The code gets the array of computer rows from the user input and segments the array with the number of segment input, then the minimum is compared for all segments in the network.
