#Suppose you have a dictionary of "cellPhone={}" with the following data 
  
 cellPhone = {} 
  
 cellPhone[0] = {"brand":"iphone", "price":5000, "sales":1266883} 
 cellPhone[1] = {"brand":"samsung", "price":3500, "sales":845869} 
 cellPhone[2] = {"brand":"nokia", "price":1200, "sales":312008} 
 cellPhone[3] = {"brand":"vestel", "price":600, "sales":76853} 
 cellPhone[4] = {"brand":"lg", "price":2860, "sales":858694} 
 cellPhone[5] = {"brand":"htc", "price":4689, "sales":288963} 
  
 # a) Write a function with the name "total" which returns the total earnings of all 6 brands 
 #(Hint: earning = price * sales) 
  
 def total(): 
     earning = 0 
     for x in range(0,len(cellPhone)): 
        earning += cellPhone[x]['price'] * cellPhone[x]['sales'] 
     return(earning) 
  
 # b) Write a function with the name "share" which adds a new "share" key to each phone in the data 
 #with the value to represent the total market share of the product 
 #(Hint: cellPhone[0] => {"brand":"iphone", "price":5000, "sales":1266883, "share":1266883*5000/total()} 
  
 def share(): 
     for y in range(0,len(cellPhone)): 
         cellPhone[y]['share'] = cellPhone[y]['sales']*total()
