Hi @Sai_SaiGraph

There’s a Python library called tailer that provides similar functionality as Linux’s tail.

A code snippet of using it is as follows:

# Get the last 3 lines of the file
tailer.tail(open('sample.log'), 3)
# ['Line 9', 'Line 10', 'Line 11']

Hope this helps!

Best regards,
Chanin

Here you are.

import tailer

for line in tailer.tail(open('sample.log'), 3):
    st.text(line)
