52. Remove Infinite Values

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
