Рассчитайте частоту каждого уникального значения серии Pandas

Опубликовано: 27 Марта, 2022

Давайте посмотрим, как найти частоту каждого уникального значения серии Pandas. Мы будем использовать функцию value_counts () для выполнения этой задачи.

Example 1 :

# importing the module
import pandas as pd
  
# creating the series
s = pd.Series(data = [2, 3, 4, 5, 5, 6, 
                      7, 8, 9, 5, 3])
  
# displaying the series
print(s)
  
# finding the unique count
print(s.value_counts())

Output :

Output:

Example 2 :

# importing the module
import pandas as pd
  
# creating the series
s = pd.Series(np.take(list("0123456789"), 
              np.random.randint(10, size = 40)))
  
# displaying the series
print(s)
  
# finding the unique count
s.value_counts()

Output :

Output:

Example 3 :

# importing pandas as pd 
import pandas as pd 
    
# creating the Series 
sr = pd.Series(["Mumbai", "Pune", "Agra", "Pune", 
                "Goa", "Shimla", "Goa", "Pune"]) 
  
# displaying the series 
print(sr) 
  
# finding the unique count
sr.value_counts()
