- Thankyou this was very helpful :) I also need to write functions that find the average_stolen using single argument called data and also write a function called get_borough_frequency where 2 arguments called borough and number and this should create a dictionary of the unique boroughs as the key and the corresponding value of total number of animals stolen in that borough .

Write a function, called CompoundInterestSchedule, that creates and returns a pandas DataFrame, where each row has: time (in years, an integer starting at 1), starting balance, interest earned, and ending balance, for an investment earning compoundedinterest. Use a for(or while) loop to create this table. The equation for theith year's ending balance is given by: Ei =Bi (1+r/f)f where: Ei is year i's ending balance Bi is year i's beginning balance (note: B1 is the amount of the initial investment (principal) r is the annual rate of interest (in decimal, e.g., 5% is .05) f is the number of times the interest rate compounds (times per year) The interest earned for a given year is Ei - Bi Note the term of the investment (in years) is not in the above equation; it is used…arrow_forward

This digit must exist in n, and it is guaranteed that n > 0, in other words, 0 will If there are multiple digits that are least occurring, return the smallest of such digits. >>> least_common (123) 1. >>> least_common (1123) 2. >>> least_common(12321) 3 Write the function least_common(n) to return the smallest digit that is least commonly occurring within n. This digit must exist in n. You should not be importing any libraries for this problem.arrow_forward8.

Answer:arrow_forwardDefine the function lake_to_tli3_dict(readings) that takes a list of (lake_name, chla, tn, tp) tuples and returns a dict mapping lake names to trophic level index values. That is, the keys are lake names and the values will be TLI3 values. Notes: You will need to have import math as your first line of code. You must include and use/call the trophic_level_index function that you wrote in Question 1. trophic_level_index must still work as specified in Question 1. Lakes should be added to the dictionary in the same order as they appear in the readings list. If a lake appears in the readings list more than once, then the TLI for the last occurrence in the readings list should be the one that appears in the result. (This should happen naturally, since the lake name can only occur in the dictionary once.) For example: Test Result names_cnp_1 = [('Lake Brunner', 0.8, 218.0, 6.0), ('Lake Carrot', 5.1, 505.0, 18.5) ] tli3_dict = lake_to_tli3_dict(names_cnp_1 ) print(tli3_dict)…arrow_forwardWhat's wrong with this cell?arrow_forward
- I need to merge three datasets so that I can create a custom function that would do the following: Create a function called theme_by_year that takes as input a year (as an integer) and shows the theme ids and theme names (listed in order by theme id) that were in sets that year. The column names must be id and name_themes (to differentiate between the name of a theme and the name of a set) in that order. The index should be reset and go from 0 to n-1. Each theme should only be listed once even if it appeared in more than one set from that year -- duplicate themes should be based on theme id and not name since there are some themes with the same name but with a different id. Hint: It will help if you were to think about merging appropriate DataFrames to help you get this answer. The desired output should look like this: theme_by_year(1960) Output: id name_themes0 371 Supplemental1 497 Books2 513 Classic Here's what I tried, but I did not get the desired output:arrow_forward+|| 8 Exercise 1 (2%) Create an anonymous block that displays a course list.
