#  Let’s start by creating a very simple mathematical function that we will call square. 
# The square function will take one number as a parameter and return the result of squaring that number. 
# Here is the black-box diagram with the Python code following.

def square(x):
    y = x * x
    return y

toSquare = 10
result = square(toSquare)

# 1)Write a function called int_return that takes an integer as input and returns the same integer.

# Answer:

def int_return(n):
    return int(n)
print(int_return(2.5)) # This line is not needed


# 2) Write a function called add that takes any number as its input and returns that sum with 2 added.

# Assessment: Dictionary Accumulation - course_2_assessment_3

# 1) The dictionary Junior shows a schedule for a junior year semester.
#    The key is the course name and the value is the number of credits.
#    Find the total number of credits taken this semester and assign it to the variable credits.
#    Do not hardcode this – use dictionary accumulation!

# Answer:

Junior = {'SI 206':4, 'SI 310':4, 'BL 300':3, 'TO 313':3, 'BCOM 350':1, 'MO 300':3}

# 2) Create a tuple called practice that has four elements: ‘y’, ‘h’, ‘z’, and ‘x’.

# Answer:

practice = 'y', 'h', 'z', 'x' 
print(practice)



# 3) Create a tuple named tup1 that has three elements: ‘a’, ‘b’, and ‘c’.

# 1) With only one line of code, assign the variables water, fire, electric, and grass to the values
# “Squirtle”, “Charmander”, “Pikachu”, and “Bulbasaur”

water, fire, electric, grass = "Squirtle", "Charmander", "Pikachu", "Bulbasaur"




# 2) With only one line of code, assign four variables, v1, v2, v3, and v4, to the following four values: 1, 2, 3, 4.

# 1) Create a tuple called olympics with four elements: “Beijing”, “London”, “Rio”, “Tokyo”.

# Amswer:

olympics = "Beijing", "London", "Rio", "Tokyo"



# 2) The list below, tuples_lst, is a list of tuples. 
# Create a list of the second elements of each tuple and assign this list to the variable country.

# Python Functions, Files, and Dictionaries - Week 4 - Assessment: More about Iteration - course_2_assessment_6



# 1) Write a function, sublist, that takes in a list of numbers as the parameter. 
# In the function, use a while loop to return a sublist of the input list. 
# The sublist should contain the same values of the original list up until it reaches the number 5 (
# it should not contain the number 5).

# 1) Create a function called mult that has two parameters, the first is required and should be an integer, 
# the second is an optional parameter that can either be a number or a string but whose default is 6. 
# The function should return the first parameter multiplied by the second.

# Answer:

mult = lambda a, b = 6: a * b

# 1) Sort the following string alphabetically, from z to a, and assign it to the variable sorted_letters.

# Answer:

letters = "alwnfiwaksuezlaeiajsdl"
sorted_letters = sorted(letters, reverse = True)



# 2) Sort the list below, animals, into alphabetical order, a-z. Save the new list as animals_sorted.
