How to print a table from a text file and fill empty spaces?

2024/11/18 9:20:27

I have the following table in a txt file:

       |Client | Container weight | Country of Origin | Product code ||S4378  |     450 Ton      | China             | 457841       ||       |     350 Ton      | Japan             | 457841       ||       |     900 Ton      | Japan             | 457841       ||       |     589 Ton      | China             | 457841       ||S4978  |    1400 Ton      | Mexico            | 457841       ||       |     980 Ton      | Emirates          | 457841       ||       |     550 Ton      | China             | 457841       ||S4578  |     450 Ton      | China             | 457841       |

The table starts in Line 81.

I want to create an output text file as follows:

       |Client | Container weight | Country of Origin | Product code ||S4378  |     450 Ton      | China             | 457841       ||S4378  |     350 Ton      | Japan             | 457841       ||S4378  |     900 Ton      | Japan             | 457841       ||S4378  |     589 Ton      | China             | 457841       ||S4978  |    1400 Ton      | Mexico            | 457841       ||S4978  |     980 Ton      | Emirates          | 457841       ||S4978  |     550 Ton      | China             | 457841       ||S4578  |     450 Ton      | China             | 457841       |

I have tried extracting lines:

file = open('containers.txt')
lines_to_print = [80, 81, 82, 83, 84, 85...]
for index, line in enumerate(file):if index in lines_to_print:print(line)

My question is how do I write this code, if my table has 300 rows?

Answer

My first suggestion would be to use a csv file, instead of this file. Is that possible for your situation? Python has a ton of libraries for parsing csv files. It's harder to parse a file when the file doesn't have a distinct character separating the different fields.

Did you export this table file from a program like SSMS? If so, they usually have support for exporting as csv instead.
