In programming, particularly in Python with the pandas library, df typically refers to a DataFrame. A DataFrame is a two-dimensional, size-mutable, and potentially heterogeneous tabular data structure with labeled axes (rows and columns). It is similar to a spreadsheet or SQL table.
Here's a brief overview:
- Creation: You can create a DataFrame from various data sources like lists, dictionaries, or CSV files.
- Usage: DataFrames are used for data manipulation and analysis, allowing operations like filtering, grouping, and aggregating data.
Example of creating a DataFrame:
import pandas as pd
data = {
'Name': ['Alice', 'Bob', 'Charlie'],
'Age': [25, 30, 35],
'City': ['New York', 'Los Angeles', 'Chicago']
}
df = pd.DataFrame(data)
print(df)
This will output:
Name Age City
0 Alice 25 New York
1 Bob 30 Los Angeles
2 Charlie 35 Chicago
