如何将熊猫系列索引日期转换为DatetimeIndex？

Question

The following data below is from a pandas series, but I need the date converted to DatetimeIndex like this format: 2020-08-17. The index of this series should be a pd.DatetimeIndex. What are some ways to convert it as such?

8/17/20    14082780.0
8/18/20    14277100.0
8/19/20    14483216.0
8/20/20    14685442.0
8/21/20    14886403.0

Answer 1

Just change the index to be as type of datetime:

df.index = pd.to_datetime(df.index)

More generally for a non-index column:

df['Date']= pd.to_datetime(df['Date'])
