Pulling data into a Pandas DataFrame

​

Example: pulling daily bars for AAPL

​

Multi-line approach

today = '2024-06-20'
oneMonthAgo = '2024-05-20'
dataset = 'daily_bars'
mySymbols = 'AAPL'
query = liberator.query(name=dataset, symbols=mySymbols, as_of=today, back_to=oneMonthAgo)
df = liberator.get_dataframe(query)

​

Single-line approach

df = liberator.get_dataframe(liberator.query(name='daily_bars', symbols='AAPL', as_of='2024-06-20', back_to='2024-05-20'))

​

Key features

• Flexible symbol input — accepts single symbols, lists, or None (all symbols)
• Granular time selection — supports daily, minute, second, and nanosecond resolution
• Simple syntax — collapsible into single-line queries for efficiency
