Number of inputs depending on another input

[El_Mehdi_Hakkou]

Hello Everyone, it’s my first time with Streamlit !
So as the title suggests, I have an input which is a number input and depending on that input, I want to add the same number of inputs.

import streamlit as st
import functions as fcts

st.title("TEST")

c=1

if c==0:
    n = int(st.session_state['nb_years'])
    residual_value = [0]*n
    residual_value[n-1] = st.number_input("Your residual_value")
    c1,c2,c3,c4 = st.columns(4)
    inv_cost = st.number_input("Your investment cost")
    invested_capital = st.number_input("Your invested capital")
    tax_rate = st.number_input("Your tax rate in percentage")
    tax_rate = tax_rate/100
    percentage_vc = st.number_input("Your variable cost in percentage")
    percentage_vc = percentage_vc/100
    with c1:
        turnover=[0]*n
        for i in range(n):
            pos = i+1
            turnover[i] = st.number_input("Your turnover for year {}".format(pos))
    with c2:
        fixed_cost = [0]*n
        for i in range(n):
            pos = i+1
            fixed_cost[i] = st.number_input("Your fixed cost for year {}".format(pos))
    with c3:
        wcr_recovery = [0]*n
        for i in range(n):
            pos = i+1
            wcr_recovery[i] = st.number_input("Your working capital requirement recovery for year {}".format(pos))
    with c4:
        wcr_variation = [0]*n
        for i in range(n):
            pos = i+1
            wcr_variation[i] = st.number_input("Your working capital requirement variation for year {}".format(pos))
    disc_rate = 0.1
    npv = fcts.process(turnover,percentage_vc,fixed_cost,inv_cost,n,invested_capital,tax_rate,wcr_recovery,wcr_variation,residual_value,disc_rate)
    st.write("Your npv", npv)

if 'nb_years' not in st.session_state:
    n = st.number_input("nb_years")
    st.session_state['nb_years'] = n
    c=0

So I thought about a lot of solutions and when I finally thought i found it, it didn’t work.
As you see here, I want that nb_years to be the first input and depending on it, I want other inputs like turnonver each year …
Please Help ! Thank you in advance !
