Dropping rows in a Data Frame

Question

I am trying to drop some specific rows in a DataFrame df where, the column Time is anything except 06:00:00 . I tried the following code but it dosen't seem to work. I even tried adding another column Index to my file to aid the process but still it is not working. Can you please help me. I am attaching the screenshots.

The val just contains the specific time 06:00:00 . Also, please ignore the variable req . Thanks a lot.

Answer 1

In pandas, by default drop isn't inplace operation. Try specifying df.drop(j, inplace=True) .

Answer 2

Have you tried?

df = df.drop(df[//expresion here//].index)

Or even better:

df = df[~df.a.str.contains("06:00:00")]

Where a is the name of the column you want to search the time in
