I have a existing dataframe, df, which consists of the following structure:
tick_id stock_ticker tick_datetime price volume
0 160939 A2M AU Equity 2016-10-19 09:00:00 450.0 79700
1 160940 A2M AU Equity 2016-10-19 09:00:01 450.0 100
2 160941 A2M AU Equity 2016-10-19 09:00:01 450.0 2500
3 160942 A2M AU Equity 2016-10-19 09:00:01 451.0 200
What I am looking to do is to set the "tick_datetime" as the index of the dataframe, so that it should become DateTimeIndex for easier data manipulation later.
However, executing the following command yields unexpected result.
df.set_index('tick_datetime')
What is the correct way to achieve my desired outcome?

Try:
df['tick_datetime'] = pd.to_datetime(df['tick_datetime'])
df.set_index('tick_datetime',inplace=True)
or:
df['tick_datetime'] = pd.to_datetime(df['tick_datetime'])
df = df.set_index('tick_datetime')
