# 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.

def mult(a, b=6):
    return a * b
    
# 2. The following function, greeting, does not work. Please fix the code so that it runs without error.
# This only requires one change in the definition of the function.

def greeting(name, greeting="Hello ", excl="!"):

# 3. Below is a function, sum, that does not work. Change the function definition so the code works.
# The function should still have a required parameter, intx, and an optional parameter, intz with a defualt value of 5.

# 4. Write a function, test, that takes in three parameters: a required integer,
# an optional boolean whose default value is True, and an optional dictionary,
# called dict1, whose default value is {2:3, 4:5, 6:8}. If the boolean parameter is True,
# the function should test to see if the integer is a key in the dictionary.
# The value of that key should then be returned. If the boolean parameter is False, return the boolean value “False”.

# {'apple': 2, 'pear': 1, 'fruit': 19, 'orange': 5, 'banana': 3, 'grapes': 2, 'watermelon': 7}.
# Write the function checkingIfIn so that when the second parameter is True,
# it checks to see if the first parameter is a key in the third parameter;
# if it is, return True, otherwise return False.

# But if the second paramter is False, then the function should check to see if the first parameter is not a key of the third.'
# If it’s not, the function should return True in this case, and if it is, it should return False.

# 6. We have provided the function checkingIfIn such that if the first input parameter is in the third,

Write a function, test, that takes in three parameters: a required integer, an optional boolean whose default value is True, and an optional dictionary, called dict1, whose default value is {2:3, 4:5, 6:8}. If the boolean parameter is True, the function should test to see if the integer is a key in the dictionary. The value of that key should then be returned. If the boolean parameter is False, return the boolean value “False”.

this can be also written as:

def test(x, y= True, dict1={2:3, 4:5, 6:8}):
if y== True:
return dict1[x]
return False

Write a function that takes the following arguments: (1) a name, (2) a value, and (3) and optional dictionary. The function adds the value to the dictionary using the name as a key in the dictionary

Create a function named get_count that:

Has two parameters:

data_list: a list of numeric values.
update_count: an optional parameter with a default value of False.
If update_count is True, this function should set the global count variable to the count of the input list data_list.

Returns the number of items of the data_list parameter.
