Validating Data Type of a Specific Column in Pandas
Pandas: Data Validation Exercise-3 with Solution
Write a Pandas program to validate the data type of a specific column in a DataFrame.
This exercise demonstrates how to validate the data type of a specific column using astype().
Sample Solution :
Code :
import pandas as pd
# Create a sample DataFrame
df = pd.DataFrame({
'ID': [1, 2, 3, 4],
'Price': ['10.5', '20.0', '30.5', '40.0']
})
# Check if the 'Price' column can be converted to float
try:
df['Price'] = df['Price'].astype(float)
print("Data type conversion successful.")
except ValueError:
print("Data type conversion failed.")
Output:
Data type conversion successful
Explanation:
- Created a DataFrame where the 'Price' column is in string format.
- Attempted to convert the 'Price' column to float using astype().
- Used try-except to handle any data type conversion errors, outputting success or failure messages.
