How do I create a DataFrame in Python using Pandas?

You can create a DataFrame using the pd.DataFrame() function. For example, pd.DataFrame(data) where data can be a dictionary, list, or another DataFrame.

Can you show me an example with a dictionary?

Sure! Here's an example:

import pandas as pd

data = {'Name': ['Alice', 'Bob'], 'Age': [25, 30]}
df = pd.DataFrame(data)
print(df)

This will create a DataFrame with two columns: Name and Age.

What if I want to create a DataFrame from a CSV file?

You can use pd.read_csv('filename.csv') to create a DataFrame from a CSV file. Just replace 'filename.csv' with your file's path.

Can I add new columns to an existing DataFrame?

Yes, you can add new columns by simply assigning a new value to a new column name, like this: df['NewColumn'] = value.
