Problem

  I have a CSV file with multiples headers and tables which was created by our system. Number of rows are dynamics but the table title name is always the same. Between each table, there's a blank row. I'm using python3.7.3 and want to get the middle table(Device table) then upload to our database.

  How can I do to get the middle table only? Can regex work with CSV file in this case?

  Original file:

    Report title:ABC
    Created Date:Jul-15-2019

    Model
    Model Name,Number
    abc,1
    abc,2

    Device
    Device Name,Number
    efg,1
    efg,2
    efg,3

    Missing Device
    Device Name,Number
    xyz,3
    xyz,4

  The table I want to have(without table name):

    Device Name,Number
    efg,1
    efg,2
    efg,3

Answer


A

C

1

=file("multiples-tables.csv").read@n()



2

=create(DeviceName,Number)



3

for A1.group@i(~=="")



4


if A3.m(2)=="Device"


5



=A3.to(4,)

6



>C5.run(A2.insert(0,string(C5.~.array().m(1)),C5.~.array().m(2)))

  A1:Read in sequence by line
  A2:Create sequence table
  A3:Grouping in empty rows
  B4:Determine whether the second item of the intra-group sequence is “Device”
  C5:Interception of required data items
  C6:Insert data item to order table
