## Pandas: DataFrame Exercise-45 with Solution

Write a Pandas program to find the row for where the value of a given column is maximum.

Sample Solution:

Python Code :

``````import pandas as pd
d = {'col1': [1, 2, 3, 4, 7], 'col2': [4, 5, 6, 9, 5], 'col3': [7, 8, 12, 1, 11]}
df = pd.DataFrame(data=d)
print("Original DataFrame")
print(df)
print("Row where col1 has maximum value:")
print(df['col1'].argmax())
print("Row where col2 has maximum value:")
print(df['col2'].argmax())
print("Row where col3 has maximum value:")
print(df['col3'].argmax())
``````

Sample Output:

```    Original DataFrame
col1  col2  col3
0     1     4     7
1     2     5     8
2     3     6    12
3     4     9     1
4     7     5    11
Row where col1 has maximum value:
4
Row where col2 has maximum value:
3
Row where col3 has maximum value:
2
```

## 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'
```
