ADTs are those data types which we use but we didn't know their inner working that is how it is working what is happening inside.It is commonly used for Data Structures for example:- In stack we use push and pop operations to insert and to delete element from a stack respectively but we didn't know how it is happening inside.How the stack is implemented and etc.Java provides most of the ADT's but not all.
 
        
             
        
        
        
Answer:
import random
def simulate_observations():
    #this generates an array of 7 numbers
    #between 0 and 99 and returns the array
    observations = random.sample(range(0, 100), 7)
    return observations
#here,we call the function created above and print it
test_array = simulate_observations()
print(str(test_array))
