Как отобразить наиболее частое значение в серии Pandas?

Опубликовано: 27 Марта, 2022

В этой статье наша основная задача - напечатать наиболее частое значение в серии. Мы можем узнать количество вхождений элементов, используя метод value_counts (). Отсюда можно получить доступ к наиболее часто используемому элементу с помощью метода mode ().

Example 1 :

# importing the module
import pandas as pd
   
# creating the series
series = 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 element
freq = series.value_counts()
print("Printing the frequency")
display(freq)
  
# printing the most frequent element
print("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 module
import pandas as pd
   
# creating the series
series = pd.Series(["g", "e", "e", "k", "s", 
                    "f", "o", "r", 
                    "g", "e", "e", "k", "s"])
  
# counting the frequency of each element
freq = series.value_counts()
  
# replacing everything else as Other
series[~series.isin(freq .index[:1])] = None
print(series)
