)

    st.write(f"{choice} is your favorite color!" if choice != 'Magenta' else f'{choice} is not a natural color!')

## Progress Bars:
'Loading...'

percentage = st.empty()
bar = st.progress(0)

for i in range(100):
    # Update the progress bar with each iteration.
    percentage.text(f'{i+1}%')
    bar.progress(i + 1)
    time.sleep(0.1)
'Loading complete!'

## Sessions:
if "counter" not in st.session_state:
    st.session_state.counter = 0

st.session_state.counter += 1

st.header(f"This page has run {st.session_state.counter} times.")
st.button("Run it again")
