Pandas Practice Set-1: Summarize only 'object' columns of the diamonds Dataframe

Pandas Practice Set-1: Exercise-6 with Solution

Write a Pandas program to summarize only 'object' columns of the 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("Summarize of 'object' columns:")
print(diamonds.describe(include=['object']))

Sample Output:

Summarize of 'object' columns:
          cut  color clarity
count   53940  53940   53940
unique      5      7       8
top     Ideal      G     SI1
freq    21551  11292   13065

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
