Python Program to Find Product of Values of elements in a Dictionary

In the previous article, we have discussed Python Program to Check if a String is a keyword or Not
Dictionary in python :

A dictionary is a set of elements that have key-value pairs. The values in the elements are accessed using the element’s keys.

example:

dict = {‘january’ :1, ‘febrauary’: 2, ‘march’: 3 }

Given a dictionary, and the task is to find the Product of values of elements in a dictionary.

Examples:

Example1:

Input:

Given dictionary = {'jan': 10, 'Feb': 5, 'Mar': 22, 'April': 32, 'May': 6}

Output:

The Product of values in a given dictionary =  211200

Example2:

Input:

Given dictionary = {'a': 1, 'b': 5, 'c': 2, 'd': 4, 'e': 7, 'f': 2}

Output:

The Product of values in a given dictionary =  560

Program to Find Product of Values of elements in a Dictionary

Below are the ways to Find the Product of Values of elements in a Dictionary.

Using For loop(Static Input)
Using For loop(User Input)

Method #1: Using For Loop (Static Input)

Approach:

Give the dictionary by initializing it with some random values and store it in a variable.
Get all the values of the given dictionary using the dictionary.values() method and store it in another variable.
Take a variable to say ‘product’ and initialize its value with ‘1’
Iterate in the above-given dictionary values using For loop.
Inside the loop, Multiply the above-initialized product variable with the iterator and store it in the same variable.
Print the product of values for the above-given dictionary.
The Exit of the program.

Below is the implementation:

# Give the dictionary as static input and store it in a variable.
gvn_dict = {'jan': 10, 'Feb': 5, 'Mar': 22, 'April': 32, 'May': 6}
# Get all the values of given dictionary using dictionary.values() method
# and store it in another variable.
dict_vlue = gvn_dict.values()
# Take a variable say 'product' and initialize it's value with '1'
fnl_prod = 1
# Iterate in the above given dictionary values using using For loop.
for itrator in dict_vlue:
  # Inside the loop, Multiply the above initialized product variable with the iterator
  # and store it in a same variable.
    fnl_prod = fnl_prod*itrator
# Print the product of values for the above given dictionary.
print("The Product of values in a given dictionary = ", fnl_prod)

Output:

The Product of values in a given dictionary =  211200

Method #2: Using For Loop (User Input)

Approach:

Take a dictionary and initialize it with an empty dictionary using dict() or {}.
Give the number of keys as user input using int(input()) and store it in a variable.
Loop till the given number of keys using for loop.
Inside the for loop scan the key and value as user input using input(), split() functions, and store them in two separate variables.
Initialize the key with the value of the dictionary.
Get all the values of the given dictionary using the dictionary.values() method and store it in another variable.
Take a variable to say ‘product’ and initialize its value with ‘1’
Iterate in the above-given dictionary values using For loop.
Inside the loop, Multiply the above-initialized product variable with the iterator and store it in the same variable.
Print the product of values for the above-given dictionary.
The Exit of the program.

Below is the implementation:

# Take a dictionary and initialize it with an empty dictionary using dict() or {}.
gvn_dict = {}
# Give the number of keys as user input using int(input()) and store it in a variable.
numb_of_kys = int(
    input('Enter some random number of keys of the dictionary = '))
# Loop till the given number of keys using for loop.
for p in range(numb_of_kys):
        # Inside the for loop scan the key and value as
    # user input using input(),split() functions
    # and store them in two separate variables.
    keyy, valuee =  input(
        'Enter key and value separated by spaces = ').split()
    # Initialize the key with the value of the dictionary.
    gvn_dict[keyy] = valuee

# Get all the values of given dictionary using dictionary.values() method
# and store it in another variable.
dict_vlue = gvn_dict.values()
# Take a variable say 'product' and initialize it's value with '1'
fnl_prod = 1
# Iterate in the above given dictionary values using using For loop.
for itrator in dict_vlue:
  # Inside the loop, Multiply the above initialized product variable with the iterator
  # and store it in a same variable.
    fnl_prod = fnl_prod*int(itrator)
# Print the product of values for the above given dictionary.
print("The Product of values in a given dictionary = ", fnl_prod)

Output:

Enter some random number of keys of the dictionary = 5
Enter key and value separated by spaces = hello 4
Enter key and value separated by spaces = this 9
Enter key and value separated by spaces = is 10
Enter key and value separated by spaces = btechgeeks 12
Enter key and value separated by spaces = python 1
The Product of values in a given dictionary = 4320
