Re: Working with Access tables and python scripts

I don't know how to start a Python script from Access, but you could definitely do it the other way around, reading the Access database from Python. An example: --- import pyodbc ODBC_DRIVER = '{Microsoft Access Driver (*.mdb)}' connstr = 'DRIVER={0};DBQ={1}'.format(ODBC_DRIVER, 'filename.mdb')

A question about numpy

I am new to numpy ... Supposing I have 2 vectors v1 and v2 and a value (constant) k. I want to build a vector r with all values of v1 greater than k and the others from v2. I found 2 ways, but not sure if they are the best solution: 1. r1=v1.copy() r2=v2.copy() r1[r1=k]=0 r=r1+r2 2. r=v1*(v1>=k
