Pandas Pivot Titanic: Extract the column labels, shape and data types of the dataset
Pandas: Pivot Titanic Exercise-2 with Solution
Write a Pandas program to extract the column labels, shape and data types of the dataset (titanic.csv). Go to Editor
Sample Solution:
Python Code :
import pandas as pd
import numpy as np
df = pd.read_csv('titanic.csv')
print("List of columns:")
print(df.columns)
print("\nShape of the Dataset:")
print(df.shape)
print("\nData types of the Dataset:")
print(df.dtypes)
Sample Output:
List of columns: Index(['survived', 'pclass', 'sex', 'age', 'sibsp', 'parch', 'fare', 'embarked', 'class', 'who', 'adult_male', 'deck', 'embark_town', 'alive', 'alone', 'Unnamed: 15'], dtype='object') Shape of the Dataset: (891, 16) Data types of the Dataset: survived int64 pclass int64 sex object age float64 sibsp int64 parch int64 fare float64 embarked object class object who object adult_male bool deck object embark_town object alive object alone bool Unnamed: 15 float64 dtype: object

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")
