In Python, What Is The Method To Obtain A Value From A Cell Within A Dataframe?

To get a value from a specific cell of a DataFrame in Python, you can use one of the following methods:

  1. Using the loc indexer:

    value = df.loc[row_index, column_name]
  2. Using the iloc indexer:

    value = df.iloc[row_index, column_index]

Here’s an example that demonstrates both methods:

import pandas as pd

# Create a sample DataFrame
data = {'Name': ['Alice', 'Bob', 'Charlie'],
        'Age': [25, 30, 35],
        'City': ['New York', 'London', 'Sydney']}

df = pd.DataFrame(data)

# Use the loc indexer to get a value based on row and column labels
value1 = df.loc[1, 'Age']
print(value1)  # Output: 30

# Use the iloc indexer to get a value based on row and column indices
value2 = df.iloc[2, 1]
print(value2)  # Output: 35

In this example, we create a DataFrame with three columns: ‘Name’, ‘Age’, and ‘City’. Using the loc indexer, we retrieve the value at row index 1 and column ‘Age’. Similarly, using the iloc indexer, we retrieve the value at the row index 2 and column index 1.
