Pandas Practice Set-1: Count how many times each value in cut series of diamonds DataFrame occurs


31. Count Occurrences in 'cut' Series

Write a Pandas program to count how many times each value in cut series of diamonds DataFrame occurs.

Sample Solution:

Python Code:

import pandas as pd
diamonds = pd.read_csv('https://raw.githubusercontent.com/mwaskom/seaborn-data/master/diamonds.csv')
print("Original Dataframe:")
print(diamonds.head())
print("\nNumber of times each value in cut series of diamonds DataFrame occurs:")
print(diamonds.cut.value_counts())

Sample Output:

Original Dataframe:
   carat      cut color clarity  depth  table  price     x     y     z
0   0.23    Ideal     E     SI2   61.5   55.0    326  3.95  3.98  2.43
1   0.21  Premium     E     SI1   59.8   61.0    326  3.89  3.84  2.31
2   0.23     Good     E     VS1   56.9   65.0    327  4.05  4.07  2.31
3   0.29  Premium     I     VS2   62.4   58.0    334  4.20  4.23  2.63
4   0.31     Good     J     SI2   63.3   58.0    335  4.34  4.35  2.75

Number of times each value in cut series of diamonds DataFrame occurs:
Ideal        21551
Premium      13791
Very Good    12082
Good          4906
Fair          1610
Name: cut, dtype: int64

  • Write a Pandas program to count the frequency of each value in the 'cut' column and display the results as a Series.
  • Write a Pandas program to compute value counts for the 'cut' series and sort them in descending order.
  • Write a Pandas program to calculate the occurrence of each cut quality and plot the frequencies as a horizontal bar chart.
  • Write a Pandas program to use value_counts() on the 'cut' column and then convert the result to a DataFrame for further analysis.
