load data from text with pandas with a two characters as separator

I'm trying to load data with pandas from a txt table. The column separator was defined as "|@" as you can see in the example:

LINEA DE NEGOCIO|@NOMBRE CLIENTE|@NUMERO CLIENTE|@NUMERO DE CONTRATO|@TIPO DE SEGURO

The system does not allow to use "|@" as separator.

Could you help me with this loading?

Thanks in advance.

I share the code:

df = pd.read_table('D:/Art_492/Encabezado.txt', sep='|@', index_col=0).astype(str)

The | represents OR operator in regular expression, you need to escape it using so updating your regex string to |@ and setting engine='python' you can get your desired result.

pd.read_table(data,sep='|@',engine='python',index_col=0).astype(str)
