Q1.Create a dict with name and mobile number.Define a GUI interface using tkinter and pack the label and create a scrollbar to scroll the list of keys in the dictionary.

from tkinter import *
root=Tk()
root.title("Users")
root.geometry('250x240')
d={'Simi':7891234123,
   'ishu':9801234456,
   'navu':8890318789,
   'kitu':7799331450,
   'noor':7348912123}

f1=Frame(root)    
f1.pack()
sb=Scrollbar(f1)
sb.pack(side=RIGHT, fill=Y)
l=Listbox(f1,yscrollcommand=sb.set)
for i in d:
   l.insert(END,i)
l.pack(side=LEFT, fill=X)
sb.configure(command=listL.yview)
root.mainloop()

Q2.In the same tkinter file as created above, create a function to insert items into the dictionary.
from tkinter import *
root=Tk()
root.title("User List!")
root.geometry('250x240')
d={'Simi':7891234123,
   'ishu':9801234456,
   'navu':8890318789,
   'kitu':7799331450,
   'noor':7348912123}

f1=Frame(root)    
f1.pack()
sb=Scrollbar(f1)
sb.pack(side=RIGHT, fill=Y)
l=Listbox(f1,yscrollcommand=sb.set)
for i in d:
   l.insert(END,i)

l.pack(side=LEFT, fill=X)
sb.configure(command=listL.yview)

#adding new entries in dictionary and updating the list
def addval():
     d[k.get()]=v.get()
     listL.insert(END,k.get())

f=Frame(root)
f.pack()
labelL=Label(f,text="Name ")
labelL.grid(row=0, column=0)
labelL=Label(f,text="Mobile No.")
labelL.grid(row=1,column=0)
k=Entry(f)
k.grid(row=0,column=1)
v=Entry(f)
v.grid(row=1,column=1)
b=Button(f,text="Add in Dictionary",command=addval)
b.grid(row=2,column=1)
root.mainloop()
