Typewriter effect in discord.py (i used google translate to ask this question, sry for any mistakes)

Question

async def type(ctx):
words = "Hello"
for x in words:
    await ctx.send(x)
    time.sleep(0.1)

Output:

H
e
l
l
o

They are not displayed in one line. What must I do to fix this problem?

Answer 1

You are sending a new message for every iteration of your loop, use Message.edit instead. Also, you need to use asyncio.sleep in place of time.sleep in async functions.

So something like:

message = None
for i in range(len(words)):
    if not message:
        message = await ctx.send(words[:i+1])
        continue

    await message.edit(content=words[:i+1])
    await asyncio.sleep(0.1)

Note that discord will likely rate limit you if you do this with longer messages.

Answer 2

This is not possible by sending messages, you need to edit them.

Example of editing your message. The only modification needed for your code, is to first send 'H' as a regular message. Then edit that message, appending a new character at a time.
