How do I get a file like object in matplotlib?

Question

I have used plt.plot(plot1['x'], plot1['y']) to produce a plot from my "plot1" dataset.

I want to get a file like object from this plot how can I get it done?

Here is the full code:

(a) Don't post code as images! (b) What should be in the filelike object? An image, maybe? In what format? — AKX, Aug 08 '21 at 18:57

BytesIO is like FileIO but with bytes instead of text. Images like png use bytes. The enables you to save your file "in memory" rather than on the disc. — mozway, Aug 08 '21 at 19:08

So, it looks like you want to save your plot as a format that can be copied in instant messaging:

import io, base64
picture = io.BytesIO()
plt.savefig(picture, format='png')
picture.seek(0)
picture_b64 = base64.b64encode(picture.read())

Solution,

import io

buf = io.BytesIO()
plt.savefig(buf, format='png')
buf.seek(0)
file = discord.File(buf, "image.png")
buf.close()
return file #  or do anything with the file
