Pandas: Split a given DataFrame into two random subsets
Pandas: DataFrame Exercise-67 with Solution
Write a Pandas program to split a given DataFrame into two random subsets.
Sample Solution :
Python Code :
import pandas as pd
df = pd.DataFrame({
'name': ['Alberto Franco','Gino Mcneill','Ryan Parkes', 'Eesha Hinton', 'Syed Wharton'],
'date_of_birth': ['17/05/2002','16/02/1999','25/09/1998','11/05/2002','15/09/1997'],
'age': ['18', '21', '22', '22', '23']
})
df_1 = df.sample(frac = 0.6)
df_2 = df.drop(df_1.index)
print("Original Dataframe and shape:")
print(df)
print(df.shape)
print("\nSubset-1 and shape:")
print(df_1)
print(df_1.shape)
print("\nSubset-2 and shape:")
print(df_2)
print(df_2.shape)
Sample Output:
Original Dataframe and shape: name date_of_birth age 0 Alberto Franco 17/05/2002 18 1 Gino Mcneill 16/02/1999 21 2 Ryan Parkes 25/09/1998 22 3 Eesha Hinton 11/05/2002 22 4 Syed Wharton 15/09/1997 23 (5, 3) Subset-1 and shape: name date_of_birth age 1 Gino Mcneill 16/02/1999 21 4 Syed Wharton 15/09/1997 23 2 Ryan Parkes 25/09/1998 22 (3, 3) Subset-2 and shape: name date_of_birth age 0 Alberto Franco 17/05/2002 18 3 Eesha Hinton 11/05/2002 22 (2, 3)

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")
