Pandas Practice Set-1: Get the true memory usage by diamonds DataFrame
Write a Pandas program to get the true memory usage by diamonds DataFrame.
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("\nTrue memory usage by diamonds DataFrame:")
print(diamonds.info(memory_usage='deep'))
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 True memory usage by diamonds DataFrame: <class 'pandas.core.frame.DataFrame'> RangeIndex: 53940 entries, 0 to 53939 Data columns (total 10 columns): carat 53940 non-null float64 cut 53940 non-null object color 53940 non-null object clarity 53940 non-null object depth 53940 non-null float64 table 53940 non-null float64 price 53940 non-null int64 x 53940 non-null float64 y 53940 non-null float64 z 53940 non-null float64 dtypes: float64(6), int64(1), object(3) memory usage: 12.4 MB None
