To create end of business month data frame from a stock data frame
0
I’m new to Python and Panda’s. I’m trying to figure out how to create a new data frame from a stock data frame that will contain only the rows for the day of the end of the business month.
Here is my Stock Data Frame:
apple = pd.read_csv("AppleStock.csv")
apple.head(10)

Convert the dates in your dataframe to datetime.
apple.index = pd.to_datetime(apple['Date'])
Use your month_index to get desired rows.
apple_month = apple.loc[month_index]
