python(vscode)/copy/deepcopy/딕셔너리 초기화

1. 코드작성

   1) deepcopy해야 변수간 연동이 안된다. 

import pandas as pd

import copy

temp_ohlcv = {'code' : [], 'min_t' : [], 'close':[]}

temp_df = pd.DataFrame(temp_ohlcv, columns=['code','min_t','close'])

minute_data_0 = {}

minute_data_0["alldata_0"] = copy.deepcopy(temp_df)  

minute_data_0["alldata_0"].loc[0] = [0,0,0]

minute_data_0["alldata_0"].loc[1] = [1,1,1]

print("첫번째 : ", minute_data_0["alldata_0"])

minute_data_0["alldata_0"] = copy.deepcopy(temp_df)  

minute_data_0["alldata_0"].loc[0] = [0,0,0]

print("두번째 : ", minute_data_0["alldata_0"])
