Unable to Update SQLite Table
#3
Sorry missed the imports and the initializations -- here you go


import import_ipynb
import talib
import numpy
import yfinance as yf
import datetime as dt
import time
from datetime import datetime, timedelta 
import sqlite3
import pandas as pd
import numpy as np
conn = sqlite3.connect('Strategy_RSI_MACD_Data.db')
c = conn.cursor()
c.execute("select DISTINCT Symbol from StockData")
tickers = c.fetchall()   
for row in tickers:
    c.execute("select [Adj Close] from StockData where Symbol = ? ", (row))
    AdjClose = c.fetchall()
    df_ta = pd.DataFrame(data = AdjClose, dtype=numpy.float64)
    df_ta = df_ta.apply(lambda c: talib.RSI(c, timeperiod = 14))
    for index, item in df_ta.iterrows():
        try:
            c.execute('''UPDATE StockData SET RSI = ? where Symbol = ? ''', (item.values, row))
        except Exception as e:
            print('Update Error: ' + str(e))
    print('Updated' + str(row))        
    conn.commit()
print ("Number of rows updated: {}".format(c.rowcount))
