Recently I started working on machine learning using python. While doing some operation on our input data using pandas package, I came across this issue. So thought of sharing here.
Below are simple steps to load a csv file and printing data frame using python pandas framework.
import pandas df = pandas.read_csv("data.csv") print(df)
This will print input data from data.csv file as below.
In the above image you can see total no.of rows are 29, but it displayed only FIVE rows. This is due to by default setting in the pandas library is FIVE rows only in my envrionment(some systems it will be 60 depending on the settings). Pandas property name to change this value is display.max_rows. We can change this value to display as many rows as you needed. If you want TEN rows to display, you can set display.max_rows property value to TEN as shown below.
pandas.set_option('display.max_rows', 10) df = pandas.read_csv("data.csv") print(df)
If we want to display all rows from data frame. We need to set this value as NONE or more than total rows in the data frame as below.
Code to set the property display.max_rows to None
pandas.set_option('display.max_rows', None) df = pandas.read_csv("data.csv") print(df)
Code to set the property display.max_rows to just more than total rows
df = pandas.read_csv("data.csv") pandas.set_option('display.max_rows', df.shape+1) print(df)
