Input parameter instead of using raw_input to write python function

My partner and I have written a def, The logic of the def is:

1. input table's field name,
2. input parameter to the parentheses(parentheses is set for some commands who needs to input string such as:

    interface fa(1)/(2)
    ip address (3) (4))

input parameter to the parentheses (if requested),then will select command from sqlite db.

    interface fa0/1
    ip address 192.168.1.1 255.255.255.0

3. Finally output commands.

Recently, my partner requests me that I have not to use input He tolds me that I must use "input parameter" And I cannot get his meaning and he will not response me about this question. I have no idea now. If anyone have know about what its mean, please provide an suggestion Thank you.

This is me and my partner python codes:

def get_input():
    a = input("function and params (comma separated):")
    b = input("device:")
    pattern = re.compile('\(.*?\)')

    output_commands = []

    params = a.split(',')

    function = params[0]

    print (params)

    counter = 1
    for result in readciscodevice(function,b):
        command = result[0]
        found_parentheses_list = re.findall(pattern, command)

        output_command = command



        for i, param_placeholder in enumerate(found_parentheses_list):

            param = params[counter]
            output_command = re.sub(pattern, param, output_command, count=1)
            counter +=1
        output_commands.append(output_command)

    return output_commands


# other program calls:

commands = get_input()

for command in commands:
    #do sth, print for example
    print(command)
