zhannawk [14.2K]

Answer:

3 parameters are passed into the function.

1 value will be returned from the function.

From the function definition "function sum(first, second, third)", we can see  that there are three value/parameters are passed in the function.Then variable "result" will be the sum all the three values. After that it will print the all three values in new line. Then the function will return one value which is the  sum of all three that is value of "result".As there is only one value returned  by the return statement in the function.

dictionary={'A':1,'B':2,'C':3,'D':4}

other_dictionary={}

for keys in dictionary:

if dictionary[keys]&1==1:

temp=dictionary[keys]*dictionary[keys]-10*10

other_dictionary[keys]=temp

else:

other_dictionary[keys]=dictionary[keys]

print(other_dictionary)  

assert other_dictionary

Explanation:

  • Initialize a sample example dictionary  and other_dictionary.
  • Do a binary comparision for checking odd number .
  • Update the the value stored in the dictionary to store the squared difference of the original value and '10'.

Describe a situation involving making a copy of a computer program or an entertainment file of some sort for which you think it
Margaret [11]

Answer:

Copying anything may be the computer program or an entertainment file, it is not a good thing as the original developers or the writers are going to feel bad since their hard work is being used by others without letting them know. However, if you are using it for academic purposes, or give them credit in your work, then the original writer will not feel that bad as he is being credited, and hence you can reuse in that case definitely, but always ensure to give the credit to the original writer.

As an example, if a film is copied like many in the past the Directors always feel bad, and they have the reason for feeling bad. The same thing is to technology.

Explanation:

The answer is self explanatory.

"Players The files SomePlayers.txt initially contains the names of 30 football play- ers. Write a program that deletes those pla
kumpel [21]

Answer:

I am writing a Python program that deletes players from the file whose names whose names do not begin with a vowel which means their names begin with a consonant instead. Since the SomePlayers.txt is not provided so i am creating this file. You can simply use this program on your own file.

fileobj= open('SomePlayers.txt', 'r')  

player_names=[name.rstrip() for name in fileobj]  

fileobj.close()  

vowels = ('a', 'e', 'i', 'o', 'u','A','E','I','O','U')

player_names=[name for name in player_names  

                     if name[0] in vowels]

fileobj.close()

print(player_names)

Explanation:

I will explain the program line by line.

First SomePlayers.txt is opened in r mode which is read mode using open() method. fileobj is the name of the file object created to access or manipulate the SomePlayers.txt file. Next a for loop is used to move through each string in the text file and rstrip() method is used to remove white spaces from the text file and stores the names in player_names. Next the file is closed using close() method. Next vowels holds the list of characters which are vowels including both the upper and lower case vowels.

player_names=[name for name in player_names  

                     if name[0] in vowels]

This is the main line of the code. The for loop traverses through every name string in the text file SomePlayers.txt which was first stored in player_names when rstrip() method was used. Now the IF condition checks the first character of each name string. [0] is the index position of the first character of each players name. So the if condition checks if the first character of the name is a vowel or not. in keyword is used here to check if the vowel is included in the first character of every name in the file. This will separate all the names that begins with a vowel and stores in the list player_names. At the end the print statement print(player_names) displays all the names included in the player_names which begin with a vowel hence removing all those names do not begin with a vowel.
