How to get a trigger from a dictionary?

Question

Python

It’s a little unclear to me how to work with dictionaries, so I want to ask you for help.
It is necessary that when sending a message that will be a key, the bot sends its value. Please tell me how this can be done.

Answer 1

First, at the expense of dictionaries: they are like lists, but instead of an index, you need to insert a key.
For example:
list:
spisok = ['hello', 'world']
print(spisok[0]) # Returns hello
dictionary:
slovar = {'hello': 'hello', 'world': 'world}
print(slovar[' hello']) # Returns hello
now about your case:
for example, you have a dictionary slv
you receive a message with the text massage_text
you need to send a message slv[massage_text] in response

Answer 2

Check for the existence of a key in the dictionary and then send its value:

if ctx.message.content in trigger_dict:
    await ctx.send(trigger_dict[ctx.message.content])
