Pandas DataFrame.head()The head() returns the first n rows for the object based on position. If your object has the right type of data in it, it is useful for quick testing. This method is used for returning top n (by default value 5) rows of a data frame or series. SyntaxDataFrame.head(n=5) Parametersn: It refers to an integer value that returns the number of rows. ReturnIt returns the DataFrame with top n rows. Example1
info = pd.DataFrame({'language':['C', 'C++', 'Python', 'Java','PHP']})
info.head()
info.head(3)
Output language 0 C 1 C++ 2 Python Example 2We have a csv file "aa.csv" that have the following dataset.
Name Hire Date Salary Leaves Remaining
0 John Idle 03/15/14 50000.0 10
1 Smith Gilliam 06/01/15 65000.0 8
2 Parker Chapman 05/12/14 45000.0 10
3 Jones Palin 11/01/13 70000.0 3
4 Terry Gilliam 08/12/14 48000.0 7
By using the head() in the below example, we showed only top 2 rows from the dataset.
# importing pandas module
import pandas as pd
# making data frame
data = pd.read_csv("aa.csv")
# calling head() method
# storing in new variable
data_top = data.head(2)
# display
data_top
