Problem Statement

Implement the below function and do not use loops in the solution

1. Find presence of allergen in a list of ingredients:

Given a list of Ingredients of a food product and an allergen. 
Find out if the list of ingredients contains the allergen or not. 
If the list contains the allergen return `True` else return `False`.

Example

Ingredients = ['Water','Soyabeans','Vitamin B12','Sugar']
Allergen = 'Soyabeans'
#returns True

Ingredients = ['mushroom','vinegar','soup thickener','sugar']
Allergen = 'peanuts'
#returns False

2. Inches to Centimeter Calculator Convert the length of a room measured in inches to centimeter and then truncate the decimal value. --| 1 inch = 2.54 centimeters |-- Example

inches_to_centi(1) #return 2
inches_to_centi(10) #return 20
inches_to_centi(-10) #return 0

3. Min-Max-Avg of list of numbers Find the Minimum,Maximum and Avergae of the list of numbers given and return a dictionary with the above as keys and their respected values. Note:- Round off the decimal to 2 places if necessary. Example

stats([12, 45, 78, 23, 56, 89]) #returns {"Minimum": 12, "Maximum": 89, "Average": 50.5}
stats([1.5, 2.5, 3.5, 4.5, 5.5]) #returns {"Minimum": 1.5, "Maximum": 5.5, "Average": 3.5}
stats([100]) #returns {"Minimum": 100, "Maximum": 100, "Average": 100.0}

    if not numbers:  
        return {"Minimum": None, "Maximum": None, "Average": None}
    
    return {
        "Minimum": min(numbers),
        "Maximum": max(numbers),
        "Average": round(sum(numbers) / len(numbers), 2)  
    }

Public Test Cases

Input 1

ingredients_list = ['milk', 'eggs', 'fish', 'Crustacean shellfish']
allergen = 'milk'
is_equal(find_allergen_presence(ingredients_list,allergen),True)

inches = 1
is_equal(inches_to_centi(inches),2)




#check_for_loops_in_solution(inches_to_centi,find_allergen_presence,stats)

Output 1

True
2
