 reduce time series based on sum condition amdi40 Programmer named Tim Posts: 15 Threads: 6 Joined: Jan 2022 Reputation: Apr-06-2022, 09:09 AM Hello i am trying to reduce the amount of zeros in a timeseries as i only need a period of 24 hour without rain before the condition does not change The script so far looks like this, but the amount of time it takes to run through this is way too long. Is there someway i can make it faster? ```import numpy as np import pandas as pd df_regn = pd.read_csv('rain_series_raw.csv', parse_dates=True, index_col=0, sep=",") n_sim = len(df_regn) # Antal tidskridt der skal simuleres total = np.zeros((n_sim)) df = np.zeros((n_sim)) for i in range(1, n_sim): total[i] = sum(df_regn.iloc[i:i - 1400, 0]) if total[i] > 0.1: df[i] = df_regn[i] else: df[i] = 5001 np.savetxt("regn23.csv", total)``` Reply
