head() method
Returns a specified number of rows from the top of a dataframe.
Syntax
dataframe_name|dataframe_name["column_name"].head(number = number_of_rows)
Parameters
| Name | Description |
|---|---|
|
number = number_of_rows optional |
The number of rows to return, or the number of values if you specify a column. If you specify a negative number, all rows in the dataframe are returned except for the bottom -n rows. If you omit the parameter, the top 5 rows are returned by default. Specifying number = is optional. |
Returns
HCL dataframe.
Examples
Return the first 5 rows from the top of a dataframe
accounts_receivable.head()
Return the first 25 rows from the top of a dataframe
accounts_receivable.head(25)
Return all rows in a dataframe except for the last one
accounts_receivable.head(-1)
Return the first 5 values from the top of a column
The values are returned from the Customer Number column as a series rather than a dataframe.
accounts_receivable["Customer Number"].head()
Remarks
HCL does not currently support the tail() method for returning rows from the bottom of a dataframe. However, you can convert the HCL dataframe to a Pandas dataframe and use tail() if you want to return bottom rows.
Return the last 10 rows from the bottom of a dataframe
import pandas as pd
accounts_receivable_pd = accounts_receivable.to_pandas()
accounts_receivable_pd.tail(10)
