## Pandas: DataFrame Exercise-52 with Solution

Write a Pandas program to remove infinite values from a given DataFrame.

Sample Solution :

Python Code :

``````import pandas as pd
import numpy as np
df = pd.DataFrame([1000, 2000, 3000, -4000, np.inf, -np.inf])
print("Original DataFrame:")
print(df)
print("Removing infinite values:")
df = df.replace([np.inf, -np.inf], np.nan)
print(df)
``````

Sample Output:

```Original DataFrame:
0
0  1000.000000
1  2000.000000
2  3000.000000
3 -4000.000000
4          inf
5         -inf
Removing infinite values:
0
0  1000.0
1  2000.0
2  3000.0
3 -4000.0
4     NaN
5     NaN
```

## Python: Tips of the Day

Creates a dictionary with the same keys as the provided dictionary and values generated by running the provided function for each value

Example:

```def tips_map_values(obj, fn):
ret = {}
for key in obj.keys():
ret[key] = fn(obj[key])
return ret
users = {
'Owen': { 'user': 'Owen', 'age': 29 },
'Eddie': { 'user': 'Eddie', 'age': 15 }
}

print(tips_map_values(users, lambda u : u['age'])) # {'Owen': 29, 'Eddie': 15}
```

Output:

```{'Owen': 29, 'Eddie': 15}
```
