Pandas get first row

As a data scientist or software engineer, you may often find yourself working with large datasets consisting of multiple groups.

In this article, we will explore some efficient and effective ways to get the first row of a Pandas dataframe based on criteria, without iterating over the entire dataframe. One of the simplest and most straightforward ways to extract the first row of a dataframe based on a specific condition is to use the. To use the. In this example, we created a sample dataframe with three columns: name , age , and city. We then used the. The output shows that the first row where the age is greater than 30 is Charlie , who is 35 years old and lives in Chicago.

Pandas get first row

We will use the DataFrame in the example below to explain how we can get the first row from a Pandas DataFrame. The pandas. The iloc property allows us to access rows and columns by their integer positions. In the given code, we are working with a Pandas DataFrame df. We use df. The output displayed to the console shows the original DataFrame and the first row we extracted. The DataFrame consists of four rows indexed from 0 to 3 and three columns, where each row represents different data. The first row, which we obtained using iloc , is displayed as a Series with column names as index labels and the corresponding values from the first row. To get the first row of a Pandas DataFrame using the pandas. In this case, 1 indicates that you want to retrieve the first row, and the result is returned as a new DataFrame containing that first row. In the given code, we are working with a Pandas DataFrame named df. To extract the first row of the DataFrame, we use the df. The code then proceeds to display the DataFrame and the first row.

She has had the opportunity to work extensively with a diverse range of technologies, including Python, Pandas, NumPy, and R.

In pandas, the head and tail methods are used to get the first and last n rows of a DataFrame , as well as the first and last n elements of a Series. Another method useful for examining data in large DataFrame or Series is sample , which randomly samples rows or columns. The pandas version used in this article is as follows. Note that functionality may vary between versions. The following DataFrame with 10 rows is used as an example. The following examples use DataFrame , but Series also supports the head and tail methods in the same manner. It is also possible to perform similar operations to head and tail using slices.
