## Pandas: DataFrame Exercise-36 with Solution

Write a Pandas program to drop a list of rows from a specified DataFrame.

Sample data:
Original DataFrame
col1 col2 col3
0 1 4 7
1 4 5 8
2 3 6 9
3 4 7 0
4 5 8 1
New DataFrame after removing 2nd & 4th rows:
col1 col2 col3
0 1 4 7
1 4 5 8
3 4 7 0

Sample Solution :

Python Code :

``````import pandas as pd
import numpy as np
d = {'col1': [1, 4, 3, 4, 5], 'col2': [4, 5, 6, 7, 8], 'col3': [7, 8, 9, 0, 1]}
df = pd.DataFrame(d)
print("Original DataFrame")
print(df)
print("New DataFrame after removing 2nd & 4th rows:")
df = df.drop(df.index[[2,4]])
print(df)
``````

Sample Output:

```Original DataFrame
col1  col2  col3
0     1     4     7
1     4     5     8
2     3     6     9
3     4     7     0
4     5     8     1
New DataFrame after removing 2nd & 4th rows:
col1  col2  col3
0     1     4     7
1     4     5     8
3     4     7     0
```

## 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'
```
