Pandas Pivot Titanic: Partition each of the passengers into four categories based on their age

Pandas: Pivot Titanic Exercise-7 with Solution

Write a Pandas program to partition each of the passengers into four categories based on their age. Go to Editor

Note: Age categories (0, 10), (10, 30), (30, 60), (60, 80)

Sample Solution:

Python Code :

import pandas as pd
import numpy as np
df = pd.read_csv('titanic.csv')
result = pd.cut(df['age'], [0, 10, 30, 60, 80])
print(result)

Sample Output:

0      (10, 30]
1      (30, 60]
2      (10, 30]
3      (30, 60]
4      (30, 60]
5           NaN

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")
