Write a program get_price. py with a function get_price() that takes a dictionary of fruits as an argument and returns the name of the most expensive fruit. Each item of the dictionary includes: A key: the name of the fruit A value: the price of the fruit.

The program is as follows:

def get_price(fruits):

   AllPrice = fruits.values()

   value_iterator = iter(AllPrice)

   mostExpensive = next(value_iterator)  

   for item in fruits:

       if fruits[item]>=mostExpensive:

           mostExpensive = fruits[item]

           fruitName = item

   print(fruitName)

fruits = {}

n = int(input("Number of Fruits: "))

for i in range(n):

   name = input("Fruit name: ")

   price = int(input("Fruit price: "))

   fruits[name] = price

get_price(fruits)

Explanation:

This defines the get_price function

def get_price(fruits):

This gets all price in the dictionary fruit

   AllPrice = fruits.values()

This passes the values to a value iterator

   value_iterator = iter(AllPrice)

This initializes mostExpensive to the first price in the dictionary

   mostExpensive = next(value_iterator)

This iterates through the elements of the dictionary  

   for item in fruits:

If current element is greater than or equals most expensive

       if fruits[item]>=mostExpensive:

Set most expensive to the current element

           mostExpensive = fruits[item]

Get the corresponding fruit name

           fruitName = item

Print fruit name

   print(fruitName)

The main begins here

This initializes the fruit dictionary

fruits = {}

This gets input for the number of fruits

n = int(input("Number of Fruits: "))

This is repeated for every inputs

for i in range(n):

Get fruit name

   name = input("Fruit name: ")

Get fruit price

   price = int(input("Fruit price: "))

Append name and price to dictionary

   fruits[name] = price

Call the get_price function

get_price(fruits)

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
