Strange artifacts while code runs

Dear colleagues,

if someone has faced the problem when launching streamlit on localhost. I run code and launch streamlit. Everything is working but while code runing the following symbols are appeared at web page (print screen is attached) {
“x”:20
“y”:120
}
{
“x”:20
“y”:120
}

Hi!

What are the unexpected symbols ? It will be great, if you paste your code here.

When you place a Python data object such as a list or a dict on a line by itself, you are implicitly calling st.write(object). So somewhere in your code, you have this object on its own line, which is what prints it to the app.
