How do you get top 5 values in python?
I am new to pandas and I would like to filter a dataframe in pandas which includes top5 values in the list. What is the best way to get the 5 values from the list with that code? Show

The solution provided by @lux7
would result in the top 5 values from a column(their values not how many times they have appeared).

In this short guide, I'll show you how to get top 5, 10 or N values in Pandas DataFrame. You can find also how to print top/bottom values for all columns in a DataFrame. If you need the most frequent values in a column or DataFrame you can check: How to Get Most Frequent Values in Pandas Dataframe To start, here is the syntax that you may apply in order to get top 10 biggest numeric values in your DataFrame:
To list the top 10 lowest values in DataFrame you can use:
In the next section, I’ll show you more examples and other techniques in order to get top/bottom values in DataFrame. Step 1: Create Sample DataFrameIn this example we are going to use real data available from Kaggle:Significant Earthquakes, 1965-2016. To learn more about reading Kaggle data with Python and Pandas: How to Search and Download Kaggle Dataset to Pandas DataFrame
data:
Step 2: Get Top 10 biggest/lowest values for single columnYou can use functions:
to get the top N highest or lowest values in Pandas DataFrame. So let's say that we would like to find the strongest earthquakes by magnitude. From the data above we can use the following syntax:
the result is:
How does it return the top 10 values? It orders all values in ascending or descending order. Then will return 5, 10 or N values from this order. Step 3: Get Top 10 biggest/lowest values - duplicatesAs you can see in Step 2 there are duplicates in the results.
which helps to deal with duplicates. Let's say that you would like to get 5 smallest values by
result:
It seems that we have many records with Depth 0. In order to get all records which have Depth 0 we can use:
the result will return the previous ones plus the duplicated:
While if we use Step 4: Get Top N values in multiple columnsYou can get top 5, 10 or N records from multiple columns with:
To do so you can use the following syntax:
result:
Step 5: How do nsmallest and nlargest workSo to summarise the algorithm:
Both methods will work only with numeric types. If you try to use them on columns with dtype object you will get an error:
Step 6: Display Top values for all numeric columns in DataFrameIf you like to get top values for all columns you can use the next syntax:
This will return the top values per column as a new DataFrame:
Step 7: nsmallest and nlargest and datetimeIt's possible to use methods If you need to convert string to datetime column you can use:
and then use the

In Python's Pandas module, the Dataframe class provides a head() function to fetch top rows from a Dataframe i.e. It returns the first n rows from a dataframe. If n is not provided then default value is 5.
How do you sort Top 5 in Python?You can use sort_values() function to sort the dataframe by column 'Age'. To sort in the descending order, you need to add parameter 'ascending=False' to this function. Then you can apply iloc to the sorted dataframe to select the top 5 rows.
How do I print the first 5 rows in Python?DataFrame. head(n) to get the first n rows of the DataFrame. It takes one optional argument n (number of rows you want to get from the start). By default n = 5, it return first 5 rows if value of n is not passed to the method.
