Selecting Columns & Rows

Need specific columns or rows? Pandas makes selection intuitive and fast:

# Single column (Series)
df['name']

# Multiple columns (DataFrame)
df[['name', 'age', 'sales']]

# Row selection with .loc (label-based)
df.loc[0:5]                    # Rows 0 to 5
df.loc[df['sales'] > 1000]     # Conditional

# .iloc (position-based)
df.iloc[0:5, 1:4]              # Rows 0-4, columns 1-3
