There once was a hat. The hat contained no rabbit, but a list of five
numbers: 1, 2, 3, 4, and
Your task is to
• write a line of code that prompts the user to replace the middle
number in the list with an integer number entered by the user
write a line of code that removes the last element from the list
(Step 2)
• write a line of code that prints the length of the existing list (Step 31.

You need to design a program for a courier company to calculate the cost of sending a parcel.
Ask the user to enter the price of the package they would like to purchase.
Ask the user to enter the total distance of the delivery in kilometers.
Now, add on the delivery costs to get the final cost of the product. There are four categories to factor in when determining a parcel’s final cost, each with two options based on the customer’s delivery preferences. (Use an if else statement based on the choice they make)
Delivery via air ($0.36 per km) or via freight ($0.25 per km)
Full insurance ($50.00) or limited insurance ($25.00)
Gift option ($15.00) or not ($0.00)
Priority delivery ($100.00) or standard delivery ($20.00)
Write code to work out the total cost of the package based on the options selected in each category.
Can anyone help?
prefixes = 'JKLMNOPQ'
suffix = 'ack'
for letter in prefixes:
print(letter + suffix)
Put this code into a Python script and run it. Notice that it prints the names "Oack" and "Qack".
Modify the program so that it prints "Ouack" and "Quack" but leaves the other names the same.
Include the modified Python code and the output in your submission.
2. Give at least three examples that show different features of string slices. Describe the feature illustrated by each example. Invent your own examples. Do not copy them for the textbook or any other source.
Weekends
Given two dates D1 and D2, write a program to count the number of Saturdays and Sundays from D1 to D2 (including D1 and D2).The date in string format is like "8 Feb 2021".
Input: The first line of input will contain date D1 in the string format.
The second line of input will contain date D2 in the string format.
Output: The output should be a single line containing two integers separated by space.
Explanation: For example, if the given dates are "25 Jan 2021" and "14 Feb 2021", the Saturdays and Sundays dates from "25 Jan 2021" to "14 Feb 2021" are
"30 Jan 2021" is a Saturday
"31 Jan 2021" is a Sunday
"6 Feb 2021" is a Saturday
"7 Feb 2021" is a Sunday
"13 Feb 2021" is a Saturday
"14 Feb 2021" is a Sunday
So the output should be
Saturday: 3
Sunday: 3

25 May 2019
22 Dec 2021Sample Output 1
Saturday: 135
Sunday: 135Secret Message - 2
Given a string, write a program to print a secret message that replaces characters with numbers 'a' with 1, 'b' with 2, ..., 'z' with 26 where characters are separated by '-'.
Note: You need to replace both uppercase and lowercase characters. You can ignore replacing all characters that are not letters.
abcdefghij12345678910
klmnopqr1112131415161718
stuvwxyz1920212223242526
Output
The output should be a single line containing the secret message. All characters in the output should be in lower case.
Explanation
For example, if the given input is "python", "p" should replaced with "16", similarly"y" with "25","t" with "20","h" with "8","o" with "15","n" with "14". So the output should be "16-25-20-8-15-14".
