Core: DataFrame

DataFrame — Pandas' core table

DataFrame is a table-like data structure with rows and columns. It's conceptually the same as an Excel spreadsheet, a database table, or a CSV file. In most Pandas projects, the DataFrame is the main object you'll be working with.

import pandas as pd

data = {
    "Name": ["Alice", "Bob", "Charlie"],
    "Age": [25, 30, 35],
    "City": ["New York", "Paris", "London"]
}

df = pd.DataFrame(data)
print(df)

The keys in the dictionary — Name, Age, City — become the column names. The values in the lists become the row data. Once you've created a DataFrame, you can select columns, filter it, and calculate statistics right away.

Name Age City 0 Alice 25 New York 1 Bob 30 Paris 2 Charlie 35 London
