How to display most frequent value in a Pandas series?
In this article, our basic task is to print the most frequent value in a series. We can find the number of occurrences of elements using the value_counts() method. From that the most frequent element can be accessed by using the mode() method.
Example 1 :
# importing the moduleimport pandas as pd # creating the seriesseries = pd.Series(['g', 'e', 'e', 'k', 's', 'f', 'o', 'r', 'g', 'e', 'e', 'k', 's'])print("Printing the Original Series:")display(series) # counting the frequency of each elementfreq = series.value_counts()print("Printing the frequency")display(freq) # printing the most frequent elementprint("Printing the most frequent element of series")display(series.mode()); |
Output :
Example 2 : Replacing the every element except the most frequent element with None.
# importing the moduleimport pandas as pd # creating the seriesseries = pd.Series(['g', 'e', 'e', 'k', 's', 'f', 'o', 'r', 'g', 'e', 'e', 'k', 's']) # counting the frequency of each elementfreq = series.value_counts() # replacing everything else as Otherseries[~series.isin(freq .index[:1])] = Noneprint(series) |
