import pandas as pd
vehicle_data = pd.read_csv('./my_test.csv')
print('self.vehicle_data:\\n', vehicle_data)
vehicle_data.set_index("TIMESTAMP", inplace=True) #TIMESTAMP를 index로 설정 loc.[x]하면 x타임스탬프 다나옴
# 将TIMESTAMP设置为index loc.[x]表示x时间戳.
print('--self.vehicle_data:\\n', vehicle_data)
sub_data = vehicle_data.loc[1]
print('sub_data:\\n', sub_data)
