#Imagine you're writing a program to check if a person is #available at a certain time.

#

#To do this, you want to write a function called

#check_availability. check_availability will have two

#parameters: a list of instances of the Meeting class, and

#proposed_time, a particular date and time.

#

#check_availability should return True (meaning the person

#is available) if there are no instances of Meeting that

#conflict with the proposed_time. In other words, it should

#return False if proposed_time is between the start_time and

#end_time for any meeting in the list of meetings.

#

#The Meeting class is defined below. It has two attributes:

#start_time and end_time. start_time is an instance of the

#datetime class showing when the meeting starts, and

#end_time is an instance of the datetime class indicating

#when the meeting ends.

#

#Hint: Instances of the datetime have at least six

#attributes: year, month, day, hour, minute, and second.

#

#Hint 2: Comparison operators work with instances of the

#datetime class. time_1 < time_2 will be True if time_1 is

#earlier than time_2, and False otherwise.

#

#You should not assume that the list is sorted.

#Here is our definition of the Meeting class:

from datetime import datetime

class Meeting:

def __init__(self, start_time, end_time):

self.start_time = start_time

self.end_time = end_time

#Write your function here!



#Below are some lines of code that will test your function.

#You can change the value of the variable(s) to test your

#function with different inputs.

#

#If your function works correctly, this will originally

#print: True, then False

meetings = [Meeting(datetime(2018, 8, 1, 9, 0, 0), datetime(2018, 8, 1, 11, 0, 0)),

Meeting(datetime(2018, 8, 1, 15, 0, 0), datetime(2018, 8, 1, 16, 0, 0)),

Meeting(datetime(2018, 8, 2, 9, 0, 0), datetime(2018, 8, 2, 10, 0, 0))]

print(check_availability(meetings, datetime(2018, 8, 1, 12, 0, 0)))

print(check_availability(meetings, datetime(2018, 8, 1, 10, 0, 0)))

Develop a program that asks the user to enter a capital for a U.S. state. Upon receiving the user input, the program reports whether the user input is correct. For this application, the 50 states and their capitals are stored in a two-dimensional array in order by state name. Display the current contents of the array then use a bubble sort to sort the content by capital. Next, prompt the user to enter answers for all the state capitals and then display the total correct count. The user's answer is not case-sensitive.

A babysitter charges $2.50 an hour until 9:00 PM when the rate drops to$1.75 an hour (the children are in bed). Write a program that accepts astarting time and ending time in hours and minutes and calculates the totalbabysitting bill. You may assume that the starting and ending times are ina single 24-hour period. Partial hours should be appropriately prorated.

Insert the missing code in the following code fragment. This fragment is intended to implement a method to set the value stored in an instance variable. Public class Employee
{
Private String empID;
Private boolean hourly;
) . .
_______
{
Hourly = isHourly;
}
}
A) public void setHourly(String isHourly)
B) public void getHourly()
C) public boolean getHourly()
D) public boolean setHourly(boolean isHourly)

A user logging on, an application server connecting to a database server, an authentication server rejecting a password, or an antivirus scanner reporting a suspected virus are all examples of:
