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

Summary

While doing this https://docs.streamlit.io/en/stable/getting_started.html

I get the above error whenever I try cols = st.columns(2)

left_column, right_column = st.columns([1,2])
pressed = left_column.button('Press me?')
if pressed:
    right_column.write("Woohoo!")

expander = st.expander("FAQ")
expander.write("Here you could put in some really, really long explanations...")

Actual behavior:

AttributeError: module ‘streamlit’ has no attribute ‘columns’ Traceback: File “c:\python\python39\lib\site-packages\streamlit\script_runner.py”, line 337, in _run_script exec(code, module.dict) File “D:_Orata_Cloud\main.py”, line 10, in <module> left_column, right_column = st.columns(2)

Is this a regression?

That is, did this use to work the way you expected in the past? no

I think it is only the version problem. upgrade and then solved it.
