Question

Exercise 7: We have two Series defined as follows: available:
import pandas as pd
s1 = pd. Series ([11, 25, 55, 10], index = ['g', 'r', 'p', 'a'])
s2 = pd. Series ([20, 30, 40])
We create a DataFrame by:
df = pd.DataFrame({"coll": 1, "col2": s2})
a) What is len(df.index)? Why?
b) Why are all the NaN values created in df?

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/

JAVA PROGRAM (Create large dataset) Create a data file with 500 lines. Each line in the file consists of a faculty member’s first name, last name, rank, and salary. The faculty member’s first name and last name for the ith line are FirstNamei and LastNamei. The rank is randomly generated as assistant, associate, and full. The salary is randomly generated as a number with two digits after the decimal point. The salary for an assistant professor should be in the range from 50,000 to 80,000, for associate professor from 60,000 to 110,000, and for full professor from 75,000 to 130,000. Save the file in Salary.txt. Here are some sample data: FirstName1 LastName1 assistant 60055.95 FirstName2 LastName2 associate 81112.45 . . . FirstName500 LastName500 full 92255.21
2. Write a function addname( ) that takes two strings, a filename, memberList.txt, and person’s name as parameters and adds the new name to the end of the list. The function will write the new file as memberList.txt. If the name is already in the list, the name will not be added.
Task 5: Unscramble You will write a program that takes in 2 files: a dictionary file and a file listing jumbled words. Your binary will be called unscramble and will be run using unscramble The file contains a bunch of scrambled words, one word per line. Your job is to print out these jumbles words, 1 word to a line. After each jumbled word, print a list of real dictionary words that could be formed by unscrambling the jumbled word. The dictionary words that you have to choose from are in the file. As an example, the starter package contains two sample input files and the result should look as follows. The order that you display the dictionary words on each line can be different; however, the order that you print out the jumbled words should be identical to the order in your input. The sample out below is skipping a few lines to save handout space (your output must not omit these lines). nwae: wean anew wane eslyep: sleepy rpeoims: semipro imposer promise ettniner: renitent.…
I already have the code for the assignment below, but there is some errors in the code. Please help me fix them. The assignment: Make a telephone lookup program. Read a data set of 1,000 names and telephone numbers from a file that contains the numbers in random order. Handle lookups by name and also reverse lookups by phone number. Use a binary search for both lookups. This assignment needs a resource class and a driver class. The resource class and the driver class will be in two separate files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code. The code needs to be written in Java. Please help me with exactly what I asked for help. The code: PhoneLookup.java import java.io.FileReader;import java.io.IOException;import java.util.Scanner; public class PhoneLookup{ public static void main(String[] args) throws IOException { Scanner in = new Scanner(System.in);…
