             Summary: [Python] Use vector append when converting from list of 
non-strided numpy arrays
                 Key: ARROW-13142
                 URL: https://issues.apache.org/jira/browse/ARROW-13142

          Issue Type: Improvement
          Components: Python
            Reporter: Krisztian Szucs
            Assignee: Krisztian Szucs
             Fix For: 5.0.0


Iterating over the numpy arrays and appending elements one by one is 
inefficient where we could rather copy the memory region instead.
