Suppose we have a dataframe named df and we want to plot a bar chart with thedata in column 'Column_1' for all the values defined in a list named 'my_list'.Select the option that has the code to execute this process?a.b.df_temp = df.loc['Column_1', my_list]plt.plot(df_temp, kind='bar', figsize=(10, 6))d.df_temp = df.loc['Column_1', my_list]df_temp.bar(figsize=(10, 6))C. df_temp=df.loc['Column_1', my_list]df_temp.plot(kind='bar', figsize=(10, 6))df_temp=df.iloc['Column_1', my_list]df_temp.plot(kind='bar', figsize=(10, 6))

option b is correct df_temp=df.loc['column_1',my_list] df_temp.bar(figsize=(10,6))

Filename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list: [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as: ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”. In this small example, we don’t achieve much of a savings (and indeed the…
We need a linked list to hold information about penguins in a zoo. You will need the following integers for your IntNode (see below). I have included sample values for one of the penguins: penguin ID: 45821 penguin weight (kg): 11 penguin height (cm): 90 We now need to track the number of penguins in the zoo. I would like to propose a better way to track the size of the list. Rather than traversing the list every time you need to know its size, why not keep a variable called listSize that increments every time you add a node to the list and decrements anytime you remove an item from the list? public class penguinList { //nested class IntNode goes here private IntNode first; private int listSize; //...the methods of penguinList class go here } Now, you just need to increment the listSize instance variable in every method that adds a node to the list. If you have any methods that removes a node from the list, decrement the listSize instance variable in those methods instead.…
Q1. The last post didnt include the items in the database. Need a different function for the python program display_ticket below: def display_tickets():t = Texttable()tickets=cur.execute('''SELECT * FROM tickets''')for i in tickets:t.add_rows([['tid', 'actual_speed','posted_speed','age','violator_sex'],list(i)])print()print(t.draw())print() Q2. Also need a different function for the python program add_ticket below: def add_tickets():actual_speed=int(input("enter actual speed:"))posted_speed=int(input("enter posted speed:"))age=int(input("enter age:"))sex=input("Male or Female:")cur.execute('''INSERT INTO tickets(actual_speed,posted_speed,age,violator_sex) VALUES(?,?,?,?)''',(actual_speed,posted_speed,age,sex))con.commit() If you'd like to see what thousands of traffic tickets look like, check out this link: https://www.twincities.com/2017/08/11/we-analyzed-224915-minnesota-speeding-tickets-see-what-we-learned/
Write a complete program that sorts dword unsigned integer array in descending order. Assume that the user doesn’t enter more than 40 integers. You MUST use the template-1-2.asm Download template-1-2.asm and follow all the directions there. Note: you have to review 3 peer assignments. You can’t add any more procedures to the template. The procedures can’t use any global variables (variables that are inside .data segment). The caller of any procedures sends its argument through the stack. Inside any procedures, if you need to use a register, you have to preserve its original value. You can't use uses, pushad operators. The callee is in charge of cleaning the stack Sample run: Enter up to 40 unsigned dword integers. To end the array, enter 0. After each element press enter: 1 4 3 8 99 76 34 5 2 17 0 Initial array: 1 4 3 8 99 76 34 5 2 17 Array sorted in descending order: 99 76 34 17 8 5 4 3 2 1 template-1-2.asm include irvine32.inc ;…

You are going to write a program (In Python) called BankApp to simulate a banking application.The information needed for this project are stored in a text file. Those are:usernames, passwords, and balances.Your program should read username, passwords, and balances for each customer, andstore them into three lists.userName (string), passWord(string), balances(float)The txt file with information is provided as UserInformtion.txtExample: This will demonstrate if file only contains information of 3 customers.
