Export contractDetails to df or csv from TWS API in Python?

This question has actually already been asked and answered on here, howwwever, the answer was given through a web link and it appears as if that link has indeed expired. Thus I am forced to ask the question again to you lovely intelligent people.

Does anyone know how to export data from "contractDetails" to a df or a csv file. This is the code so far:

class TestApp(EWrapper, EClient):
def __init__(self):
EWrapper.__init__(self)
EClient.__init__(self, self)​

def contractDetails(self, reqId, contractDetails):
self.data =[contractDetails]
df = pd.DataFrame(self.data)
df.to_csv('options_test.csv')
print(df)​

def contractDetailsEnd(self, reqId):
print("\ncontractDetails End\n")​

def start(self):
contract =Contract()
contract.symbol ='AAPL'
contract.secType ='OPT'
contract.exchange ='SMART'
contract.currency ='USD'
#contract.primaryExchange = 'NASDAQ'
contract.lastTradeDateOrContractMonth ='202010'
#contract.strike = 175
#contract.right = "C"
#contract.multiplier = "100"
global underlying
underlying = contract.symbol​

self.reqMktData(1, contract,'106',False,False,[])​

self.reqContractDetails(1, contract)​

def stop(self):
self.done =True
self.disconnect()​

def main():
app =TestApp()
app.nextOrderId =0
app.connect('127.0.0.1',7497,123)
app.data =[]​

Timer(4, app.stop).start()
app.run()​

if __name__ =="__main__":
main()​

If anyone can figure this out, be rest assured, dinner is on me (Y)

Thank you for your time.

@2rosy you are a legend, what is your account details?

 

To prevent this issue from reoccurring in the future for someone else, here is the syntax that I am using based off of the answer @2rosy provided me with:

from ib_insync import *
util.startLoop()

import logging
# util.logToConsole(logging.DEBUG)

ib = IB()
ib.connect('127.0.0.1', 7497, clientId=1)


spy = Option('SPY', '202301', '', 'C', 'SMART')

cds = ib.reqContractDetails(spy)

len(cds)

contracts = [cd.contract for cd in cds]

contracts[0]

util.df(contracts)

print(util.df(contracts))​

Thank you again @2rosy!
