How to print pandas DataFrame without index

I want to print the whole dataframe, but I don't want to print the index

Besides, one column is datetime type, I just want to print time, not date.

The dataframe looks like:

       User ID           Enter Time   Activity Number
    0      123  2014-07-08 00:09:00              1411
    1      123  2014-07-08 00:18:00               893
    2      123  2014-07-08 00:49:00              1041

I want it print as

    User ID   Enter Time   Activity Number
    123         00:09:00              1411
    123         00:18:00               893
    123         00:49:00              1041
    print df.to_string(index=False)
