Suppose we have a dataframe named df and we want to plot a bar chart with the data 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? b. O C. d. df_temp=df.loc['Column_1', my_list] plt.plot(df_temp, kind='bar', figsize=(10, 6)) df_temp = df.loc['Column_1', my_list] df_temp.bar(figsize=(10, 6)) 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))

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/
