Question

Magnolia resident’s association registers who holds different positions in a text variable MA.

PS: Remember that triple quotation marks """…""" is used for texts that go over several lines.

MA=        \

"""

Magnolia resident’s association

leader: Kathy

cashier: Jack

IT guy: Richard

parking manager: Kathy

event manager: Richard

maintenance manager: Kathy

fire safety manager: Kathy

"""

Develop a function which returns the list over the positions a person holds.

>>> position(«Richard»)

[«IT guy», «event manager»]

Answer 1

Find the python code below. I have written comments for every line. Also, you can find a sample output screenshot at the end of the answer.

# given string
MA=        \
"""
Magnolia resident’s association
leader: Kathy
cashier: Jack
IT guy: Richard
parking manager: Kathy
event manager: Richard
maintenance manager: Kathy
fire safety manager: Kathy
"""

# define function
def position(x):
    
    # split the string into an array by new line character
    registers = MA.split("\n")

    # Discard lines which do not contain a ":" (position: name format should be followed)
    registers = [i for i in registers if ":" in i]

    # declaring a dictionary, key = name, value = array of positions
    d = dict()

    # iterate over the registers array, split by ": " and add to dictionary
    for i in registers:
        i = i.split(": ")

        if i[1] in d: # name in dictionary
            d[i[1]].append(i[0])
        else: # name not in dictionary
            d[i[1]] = [i[0]]

    return d[x]

# invoke function
print(position("Richard"))

Thanks & Regards.
