the file “catalogo_no_linebreak.txt” contains a list of products, grouped in one line, i’am using the regular expression (re.split()) to try
Retrieve the record of each product and logo after saving to the “saida.txt” file.

The txt_format() function is where I process and use the regular expression “result = re.split(r’,00′, arq.readline())”.

The way I’m using the regular expression with product records that are returning incomplete, we can see it highlighted in red.

How can I retrieve the content of each product that is in the pattern “0453. [content] ,00”?
