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
Sample Input 1
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".

add two polynomials given two polynomials a and b, write a program that adds the given two polynomials a and b. input the first line contains a single integer m. next m lines contain two integers pi, ci separated with space, where pi denotes power and ci denotes co-efficient of pi for polynomial a. after that next line contains a single integer n. next n lines contain two integers pj, cj separated with space, where pj denotes power and cj denotes co-efficient of pj for polynomial b.
Please help me for this i am not able to do this
3. Disarium Number
A number is said to be Disarium if the sum of its digits raised to their respective positions is the number itself.
Example:
75
7^1+5^2=7+25=32 → False
135
1^1+3^2+5^3=1^9+125=135 → True
Print True if a number is a Disarium, otherwise print False.
Input
The Input will be any integer
135
Output
True

How to print 0 in the code for this question since i am trying this question from last 1 mnth i am not passing test casses please help me to do this
example below)The only input to the program is the name of the file. output is the file "output.txt".
rules
The first 4 digits of the ID card is the birth year.
The next 3 digits are the number of days to the birth date from January 1st of that year. If the person is a female, 500 is added to that value.
The next three digits are assigned to submission for a particular birth year. input file contains the records of submission where each attribute is space separated.
In example , Aruni is the second entry in year 1990. Therefore the last three digits of NIC are 002.Assume there are only 999 entries per year.
Example:
Input file output file
Saman 1990-05-03 M Saman 1990123001
Aruni 1990-04-06 F Aruni 1990596002
Nazar 1997-09-24 M Nazar 1997267001
