Break down this @client.command() snippet

Question

I am trying to modify the following code but I've come to the conclusion I don't fully understand what is taking place here. If someone would be so kind as to break it down for me line by line I'd be appreciative.

@client.command(name='cmd')
async def cmd(context):
    command = context.message.content.replace("!cmd ", "")
    word_list = command.split()
    if word_list[0] == str(ID):
        word_list.pop(0)
        final_command = " ".join(word_list)

Answer 1

command = context.message.content.replace("!cmd ", "")

Removes !cmd from the message by replacing it with an empty string

word_list = command.split()

Splits the message into a list, each word in the message as an item in the list

if word_list[0] == str(ID):
        word_list.pop(0)
        final_command = " ".join(word_list)

If the first word is an ID (str(ID) converts the ID to a string it so it can be compared) then remove it from the list. Then combine the words in the list back into a string, joined by spaces.
