## 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

Join Strings in an Iterable:

```>>> words = ('Hello', 'Python', 'Programmers')
>>> '!'.join(words)
'Hello!Python!Programmers'
>>> words_dict = {0: 'zero', 1: 'one', 2: 'two', 3: 'three'}
>>> '&'.join(words_dict.values())
'zero&one&two&three'
```
