AttributeError: module 'streamlit' has no attribute 'beta_columns'

Hi,
I was trying to lay out the dropdown into columns but when I use the function st.beta_columns() I get an attribute error stating module ‘streamlit’ has no attribute ‘beta_columns’. Can someone help me with this issue.

streamlit version : 0.73.0
python version : 3.7.9

Based on your print screen, it looks like you’re running on python 3.8 right? Click on the hamburger menu and then select about. which version of streamlit are you getting?
