作业1:
import time
import pandas as pd
from jqdatasdk import *

转换周期: 日K转换为月K

df = get_price(‘000001.XSHE’, start_date=‘2021-01-01’,end_date=‘2021-01-29’,
frequency=‘daily’,panel=False)# 获取日K

#添加一行
df[‘month’] = df.index.month

df_month = pd.DataFrame()

df_month[‘open’] = df[‘open’].resample(‘M’).first()
df_month[‘close’] = df[‘close’].resample(‘M’).last()
df_month[‘high’] = df[‘high’].resample(‘M’).max()
df_month[‘low’] = df[‘low’].resample(‘M’).min()

print(df_month)
输出:

第二题:
import time

from jqdatasdk import *

df = get_price(‘000001.XSHE’, start_date=‘2020-01-01’,end_date=‘2020-12-31’,
frequency=‘daily’,panel=False)# 获取日K

df[‘month’] = df.index.month

df_month = pd.DataFrame()

df_month[‘volume’] = df[‘volume’].resample(‘M’).sum()
df_month[‘money’] = df[‘money’].resample(‘M’).sum()

print(df_month)

输出:
