Get the first 3 rows of a given DataFrame

Let us first create a dataframe and then we will try to get first 3 rows of this dataframe using several methods.

Code: Creating a Dataframe.

Output:

Output of above code: Dataframe created

Getting first 3 Rows of the above Dataframe :

Method 1: Using head(n) method.

This method returns top n rows of the dataframe where n is an integer value and it specifies the number of rows to be displayed. The default value of n is 5 therefore, head function without arguments gives the first five rows of the dataframe as an output. So to get first three rows of the dataframe, we can assign the value of n as ‘3’. 

Syntax: Dataframe.head(n)

Below is the code for getting first three rows of the dataframe using head() method:

Output:

Output of above code:- first three rows of the dataframe using head() function

Method 2: Using iloc[ ].

This can be used to slice a dataframe by using the starting index and ending index of the sliced dataframe that we want.

Syntax: dataframe.iloc[statrt_index, end_index+1]

So if we want first three rows, i.e. from index 0 to index 2, we can use the following code:

Output of above code:- First three rows of the dataframe using iloc[] method

Method 3: Using index of the rows.

 iloc[ ] method can also be used by directly stating the indices of the rows we want in the iloc method. Say to get row with indices m and n iloc[ ] can be used as:

Syntax: Dataframe.iloc [ [m,n] ]

Following is the code to get first three rows of the dataframe using this method:

Output:

Output of the above code:- First three rows of the dataframe using iloc and indices of the desired rows.
