• t is time in days since January 1, 1980
- T(t) is the temperature in degrees Fahrenheit at time t.
our task is to write a script that creates a symbolic function Tavg(ndays) which returns the average temperature at this location over ndays, where ndays corresponds to the
umber of days elapsed since 1/1/1980. The symbolic variables t and ndays have already been defined for you. Complete the script by following the steps below:
1. Define the numeric function T(t) using the formula above.
2. Use T and the int function to define the symbolic function Tavg(ndays).
3. The number of days between 1/11980 and 1/1/2000 has been computed for you and is stored in the variable days2000. Use Tavg and days2000 to compute the average
temperature from 1980 until 2000 and store the result in the variable T2000. Convert Tavg2000 to a numeric value using the double function.

Write a program that generates random numbers between -25 and 25 by using the randint function. The program will add up the numbers and terminate when the sum of the values becomes zero. The program should contain the following functions: add() : add up the values main(): the function where the program execution should begin and end. randomgen(): a function that returns a number between -25 and 25 A global variable subsetsum that keeps track of the sum The program should output the count of the number of values generated before exiting saying that the subset sum was zero.

A number is said to be Harshad if it's exactly divisible by the sum of its digits. Create a function that determines whether a number is a Harshad or not. Examples isHarshad (75) → false // 7 + 5 = 12 // 75 is not exactly divisible by 12 isHarshad (171) → true // 1 + 7 + 1 = 9 // 9 exactly divides 171 isHarshad (481) → true isHarshad (89) → false isHarshad (516) → true isHarshad (200) → true
Compute and Plot the ROC Curve Write a function from scratch called roc_curve_computer that accepts (in this exact order): a list of true labels a list of prediction probabilities (notice these are probabilities and not predictions - you will need to obtain the predictions from these probabilities) a list of threshold values. The function must compute and return the True Positive Rate (TPR, also called recall) and the False Positive Rate (FPR) for each threshold value in the threshold value list that is passed to the function. Important: Be sure to reuse functions and code segments from your work above! You should reuse two of your above created functions so that you do not duplicate your code. The function you will write behaves identically to Scikit-Learn's roc_curve function, except that it will take the list of thresholds in as input rather than return them as output. Your function must calculate one value of TPR and one value of FPR for each of the threshold values in the list.…
Problem DNA: Subsequence markingA common task in dealing with DNA sequences is searching for particular substrings within longer DNA sequences. Write a function mark_dna that takes as parameters a DNA sequence to search, and a shorter target sequence to find within the longer sequence. Have this function return a new altered sequence that is the original sequence with all non-overlapping occurrences of the target surrounded with the characters >> and <<. Hints: ● String slicing is useful for looking at multiple characters at once. ● Remember that you cannot modify the original string directly, you’ll need to build a copy. Start with an empty string and concatenate onto it as you loop. Constraints: ● Don't use the built-in replace string method. All other string methods are permitted. >>> mark_dna('atgcgctagcatg', 'gcg') 'at>>gcg<<ctagcatg' >>> mark_dna('atgcgctagcatg', 'gc')…

You may assume that the second time will always be after the first time, both times will always be on the same date, and military time will be used (no a.m. or p.m.). Examples time_delta(04:15:36, 16:35:27) ➞ (12:19:51) time_delta(02:06:05, 06:09:10) ➞ (04:03:05) Sample Input 1 "04:15:36" "16:35:27" Sample Output 1 "12:19:51"
