How to select certain number of rows in data frame?

Question

So I have a dataframe that is (2624229, 574) and I would like to select only the first 864000 rows, but I can't figure out how to do it.

Thank you.

Answer 1

One of possible solutions is to use iloc :

n = 864000
df.iloc[:n]

The above code retrieves initial n rows (for now df holds all rows). But if you want to drop all rows beyond this limit, run:

df = df.iloc[:n]
