When new members join our team, they usually are already fluent in data analysis with pandas and know their way around the typical quirks. They know that they should use vectorised functions where possible and avoid using apply with a slow Python callable.

The following are 30 code examples for showing how to use pandas.core.internals.BlockManager().These examples are extracted from open source projects. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example.
The primary benefit of the BlockManager is improved performance on certain operations (construction from a 2D array, binary operations, reductions across the columns), especially for wide DataFrames. However, the BlockManager substantially increases the complexity and maintenance burden of pandas. By replacing the BlockManager we hope to achieve
