# Pandas Practice Set-1: Rename two of the columns of the diamonds Dataframe

## Pandas Practice Set-1: Exercise-7 with Solution

Write a Pandas program to rename two of the columns of the diamonds Dataframe.

Sample Solution :

Python Code :

``````import pandas as pd
print("Original Dataframe:")
print("\nAfter renaming two of the columns of the said dataframe:")
diamonds.rename(columns={'color':'diamond_color', 'clarity':'dimaond_clarity'}, inplace=True)
``````

Sample Output:

```Original Dataframe:
carat      cut color clarity  depth  table  price     x     y     z
0   0.23    Ideal     E     SI2   61.5   55.0    326  3.95  3.98  2.43
1   0.21  Premium     E     SI1   59.8   61.0    326  3.89  3.84  2.31
2   0.23     Good     E     VS1   56.9   65.0    327  4.05  4.07  2.31

4   0.31     Good     J     SI2   63.3   58.0    335  4.34  4.35  2.75

After renaming two of the columns of the said dataframe:
carat      cut diamond_color dimaond_clarity  ...   price     x     y     z
0   0.23    Ideal             E             SI2  ...     326  3.95  3.98  2.43
1   0.21  Premium             E             SI1  ...     326  3.89  3.84  2.31
2   0.23     Good             E             VS1  ...     327  4.05  4.07  2.31
3   0.29  Premium             I             VS2  ...     334  4.20  4.23  2.63
4   0.31     Good             J             SI2  ...     335  4.34  4.35  2.75

[5 rows x 10 columns]
```

## Python: Tips of the Day

Checks if the given number falls within the given range.

Example:

```def tips_range(n, start, end = 0):
return start <= n <= end if end >= start else end <= n <= start
print(tips_range(2, 4, 6))
print(tips_range(4, 8))
print(tips_range(1, 3, 5))
print(tips_range(1, 3))
```

Output:

```False
True
False
True
```
