Numerical Computing with Python

Appending new rows to DataFrames

When performing a data analysis, it is far more common to create new columns than new rows. This is because a new row of data usually represents a new observation and, as an analyst, it is typically not your job to continually capture new data. Data capture is usually left to other platforms like relational database management systems. Nevertheless, it is a necessary feature to know as it will crop up from time to time.
