# Pandas Practice Set-1: Sort the entire diamonds DataFrame by the 'carat' Series in ascending and descending order

## Pandas Practice Set-1: Exercise-14 with Solution

Write a Pandas program to sort the entire diamonds DataFrame by the 'carat' Series in ascending and descending order.

Sample Solution :

Python Code :

``````import pandas as pd
print("Original Dataframe:")
print("\nSort the entire diamonds DataFrame by the 'carat' Series in ascending order")
result = diamonds.sort_values('carat')
print(result)
print("\nSort the entire diamonds DataFrame by the 'carat' Series in descending  order")
result = diamonds.sort_values('carat', ascending=False)
print(result)
``````

Sample Output:

```Original Dataframe:

Python: The Zip() Function

```>>> students = ('John', 'Mary', 'Mike')
>>> ages = (15, 17, 16)
>>> scores = (90, 88, 82, 17, 14)
>>> for student, age, score in zip(students, ages, scores):
...     print(f'{student}, age: {age}, score: {score}')
...
John, age: 15, score: 90
Mary, age: 17, score: 88
Mike, age: 16, score: 82
>>> zipped = zip(students, ages, scores)
>>> a, b, c = zip(*zipped)
>>> print(b)
(15, 17, 16)
```
