Chapter 7, Problem 4TF
Explanation of Solution
Copying lists:
- • In Python, to copy a list to another list, simply assign the list to be copied to another list
- • Both the lists will be identical as they refer to the same object in the memory.
Example program:
#Create a list of strings
slist1 = ['Jack', 'John', 'James']
#Copy slist1 to slist2
slist2 = slist1
#Print the slist1
print(slist1)
#Print the slist2
print(slist2)
#Change a string in slist2
slist2[1] = 'Jacob'
#Print the slist1
print(slist1)
#Print the slist2
print(slist2)
Sample output:
['Jack', 'John', 'James']
['Jack', 'John',...

program7.pyThis assignment requires the main function and a custom value-returning function. The value-returning function takes a list of random integers as its only argument and returns a smaller list of only the elements that end with 7. This value-returning function must use a list comprehension to create this smaller list.In the main function, code these steps in this sequence:
Set random seed to 42 import randomrandom.seed(42)
create an empty list that will the hold random integers.
use a loop to add 50 random integers to the list. All integers should be between 200 and 250, inclusive. Duplicates are okay.
sort the list in ascending order and then use another loop to display all 50 sorted integers on one line separated by spaces.
print a slice showing list elements indexed 5 through 10, inclusive.
print a second slice showing the final 5 elements in the sorted list.
