    Do you mean you want to get the 10000000 out of some line=”[aln-core]:10000000 sequences have been processed”?

    If you’re sure that line’s always going look like that, try 

    line.split(':')[1].split[0]

    I mean …

    line = "[aln-core]:10000000 sequences have been processed"

line.split(':')[1]
'10000000 sequences have been processed'

line.split(':')[1].split()[0]
'10000000'
