Question

You are an administrator. You want to track some of the courses being offered. Write a python program that will allow you to enter four pieces of information:

• The course number
• The room number
• The instructor
• The meeting time

Use 3 dictionaries (rooms, instructors, times) to store this information. The course number would be the key in the three dictionaries, and the other items would be the values.

Allow for six courses and their associated items.

After creating the dictionaries , ask the user what to search for. When you search for one of the items, the other three will be found and printed.

Write a menu to allow the user to choose which item to search for. And after it printed, ask the user if they want to continue.

Answer 1

code.py

def finditems(dic1, item):
res =0;
print()
for key, value in dic1.items(): # for name, age in dictionary.iteritems(): (for Python 2.x)
if value == item:
print("course:", key)
print("room : ",rooms[key])
print("instructor : ",instructors[key])
print("meeting time : ",times[key])
print()
res +=1
print("Results found :", res)
print()

rooms = {'CS101':'204','CS102':'108','EC201':'204','M101':'301','M102':'402', 'CS103':'309'}
instructors = {'CS101':'John Doe','CS102':'Khaleesi','EC201':'Harry potter','M101':'Frodo','M102':'Yoda', 'CS103':'Harry potter'}
times = {'CS101':'17:00','CS102':'15:30','EC201':'14:00','M101':'11:30','M102':'10:00', 'CS103':'08:30'}

while(True):
x = input("1 for rooms\n2 for instructor\n3 for time\nAny other key to exit\nwhat items you want to search : ")
if x =="1":
r = input("enter room number: ")
finditems(rooms,r)
elif x== "2":
i = input("enter instructur to serach :")
finditems(instructors,i)
elif x=="3":
t = input("enter time to serach (hh:mm 24hr format):")
finditems(times,t)
else:
print("exiting")
break
