Part 2
Write a function named test_sqrt that prints a table like the following using a while loop, where "diff" is the absolute value of the difference between my_sqrt(a) and math.sqrt(a).
a = 1 | my_sqrt(a) = 1 | math.sqrt(a) = 1.0 | diff = 0.0
a = 2 | my_sqrt(a) = 1.41421356237 | math.sqrt(a) = 1.41421356237 | diff = 2.22044604925e-16
a = 3 | my_sqrt(a) = 1.73205080757 | math.sqrt(a) = 1.73205080757 | diff = 0.0
a = 4 | my_sqrt(a) = 2.0 | math.sqrt(a) = 2.0 | diff = 0.0
a = 5 | my_sqrt(a) = 2.2360679775 | math.sqrt(a) = 2.2360679775 | diff = 0.0
Modify your program so that it outputs lines for a values from 1 to 25 instead of just 1 to 9.
You should submit a script file and a plain text output file (.txt) that contains the test output. Multiple file uploads are permitted.
Part 1
Encapsulate the following Python code from Section 7.5 in a function named my_sqrt that takes a as a parameter, chooses a starting value for x, and returns an estimate of the square root of a.
while True:
y = (x + a/x) / 2.0
if y == x:
break
x = y
Each of the following Python functions is supposed to check whether its argument has any lowercase letters.
For each function, describe what it actually does when called with a string argument. If it does not correctly check for lowercase letters, give an example argument that produces incorrect results, and describe why the result is incorrect.
# 3
def any_lowercase3(s):
for c in s:
flag = c.islower()
return flag
# 4
def any_lowercase4(s):
flag = False
for c in s:
flag = flag or c.islower()
return flag
# 5
def any_lowercase5(s):
for c in s:
if not c.islower():
return False
return True
This assignment is based on Exercise 8.4 from your textbook. Each of the following Python functions is supposed to check whether its argument has any lowercase letters.
For each function, describe what it actually does when called with a string argument. If it does not correctly check for lowercase letters, give an example argument that produces incorrect results, and describe why the result is incorrect.
# 1
def any_lowercase1(s):
for c in s:
if c.islower():
return True
else:
return False
# 2
def any_lowercase2(s):
for c in s:
if 'c'.islower():
return 'True'
else:
return 'False'
Add two polynomials
Given two polynomials A and B, write a program that adds the given two polynomials A and B
Output
Print the addition of polynomials A and B.
If the degree of polynomial is zero and the constant term is also zero, then just print 0 to represent the polynomial.
For term Cix^Pi, if the coefficient of the term Ci is 1, simply print x^Pi instead of 1x^Pi.Explanation

You have store a record of students in a file record.txt. To make a file: Make a function to write in a file write_data().Each record contains the student's name, and there marks in Maths, Physics and Chemistry out of 100(write a check to ensure the entered marks is in range 0-100, if user enters marks out of this range, ask the user to re-enter the marks ). The marks can be floating values. The user enters names and marks for students. You are required to save the record in a record.txt. Once you done with the making file. Make a function read_data(d) that takes empty dictionary as a parameter Read the data from record.txt and add it into dictionary as a name and percentage The user then enters a student's name. Output the name, average percentage marks obtained by that student, correct to two decimal places and on the basis of marks display grades as well
Weighted final score Final grade 80 <= mark <= 100 A 70 <= mark < 80 B 60 <= mark < 70 C 50 <= mark < 60 D mark < 50 E
IPL Match Details
Write a program that reads all the match outcomes and summarizes the information of all the matches.
Points are given to the teams based on the outcome of the match.
A win earns a team 3 points. A draw earns 1. A loss earns 0.
The following information is expected:
MP: Matches Played
W: Matches Won
D: Matches Drawn (Tied)
L: Matches Lost
P: Points
The team information should be displayed in descending order of points.
Input
The first line contains a single integer N, denoting the total no. of matches played.
Names of teams may contain spaces but will be less than 24 characters
100 >= N >= 0
Sample Input
6
CSK;RR;loss
RR;DD;draw
MI;KKR;win
KKR;RR;loss
CSK;DD;draw
MI;DD;draw
Sample Output
Team: RR, Matches Played: 3, Won: 2, Lost: 0, Draw: 1, Points: 7
Team: MI, Matches Played: 2, Won: 1, Lost: 0, Draw: 1, Points: 4
Team: DD, Matches Played: 3, Won: 0, Lost: 0, Draw: 3, Points: 3
Team: CSK, Matches Played: 2, Won: 0, Lost: 1, Draw: 1, Points: 1
Team: KKR, Matches Played: 2, Won: 0, Lost: 2, Draw: 0, Points: 0Smallest Missing Number
Given a list of numbers, write a program to print the smallest positive integer missing in the given numbers.
Input
The input will be a single line containing numbers separated by space.
Output
The output should be a single line containing the smallest missing number from given numbers.
Explanation
For example, if the input numbers are 3, 1, 2, 5, 3, 7, 7.
The number 1, 2, 3 are present. But the number 4 is not. So 4 is the smallest positive integers that is missing from the given numbers.
Sample Input 1
3 1 2 5 3 7 7
Sample Output 1
4
Sample Input 2
5 5 2 3 1 8 8 4
Sample Output 2

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 Jan 2021
14 Feb 2021
Sample Output 1
Saturday: 3
Sunday: 3
Sample Input 2
25 May 2019
22 Dec 2021
Sample Output 2
Saturday: 135
Sunday: 135
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.
Explanation
If M = 4 and for polynomial A
For power 0, co-efficient is 5
For power 1, co-efficient is 0
For power 2, co-efficient is 10
For power 3, co-efficient is 6.
If N = 3 and for polynomial B
For power 0, co-efficient is 1
For power 1, co-efficient is 2
For power 2, co-efficient is 4.
Then polynomial A represents "6x^3 + 10x^2 + 5", the polynomial B represents "4x^2 + 2x + 1" and the addition of A and B is "6x^3 + 14x^2 + 2x + 6"
Sample Input

0 5
1 0
2 10
3 6
3
0 1
1 2
2 4
Sample Output
6x^3 + 14x^2 + 2x + 6
