By using Python code:

1. list1 = ['smith', 'john', 'andy']
list2 = ['kim', 'mary', 'paul']
Write a python program which does the following:

a. add items in list2 to list1
b. Remove mary from list1
c. Insert sam at 5th position
d. Sort the elements of list1 in ascending order

2. Write a python program that asks the user to enter a sentence and creates a list of words in that sentence.

3. friends = ('sam','andy','mary','andy','john','andy','mary')
Write a python program which does the following:

a. for the above string calculate the number of times "andy" appears in the tuple

b. change sam with smith

c. print index of john

Expert Solution

Q1

for i in list2:
list1.append(i)

list1.remove('mary')
list1.insert(5,'sam')
list1.sort()
print(list1)

The output is

Q2

string=input('Enter a sentence')
words=list(set(string.split()))#set is used to get unique words from sentence
print(words)

Q3

friends = ('sam','andy','mary','andy','john','andy','mary')
count=0
for i in friends:
if i=='andy':
count+=1
print('Andy appears',count,'times')

temp=list(friends)
temp[0]='smith'
friends=tuple(temp)
print(friends)
print(friends.index('john'))

The output is -

This program is about list comprehension. list1 = [2, 5, 7, 8] list2 = [1, 2] (e) Use nested list comprehension with list1 and list2 as input sequences to generate this list: [[3, 4], [6, 7], [8, 9], [9, 10]] Display the list. The following is the expected output. Part e: [[3, 4], [6, 7], [8, 9], [9, 10]]

write a Python program (with comments) to do the following: Define a list list1 = [['Rose', 'Daisy'], 7, 0, 5.5, [1, 22, 2.45, 3, 6, 5.8]] and print it. Print the length of list1 (i.e. number of items in list1) with a suitable message. Print the first character of the first string in the first item of list1 with a suitable message (HINT: The first item is the item with index 0). Print the sum of the last 4 numbers...

"PYTHON" Write some code " USING PYTHON" to keep reading numbers from the user until the users enters a negative number. The program then prints out: a) the sum of all the numbers b) the average of all the numbers c) the max of the numbers d) the min of the numbers Note we did not cover lists (array) so you will not use them in this problem. Finally, ask the user for their name, then print their name as...

(Python) a) Using the the code below write a function that takes the list xs as input, divides it into nss = ns/nrs chunks (where nrs is an integer input parameter), computes the mean and standard deviation s (square root of the variance) of the numbers in each chunk and saves them in two lists of length nss and return these upon finishing. Hint: list slicing capabilities can be useful in implementing this function. from random import random as rnd...
