How to remove sequences from a fasta file using a sequence ID list which contains a space within the id? I have a fasta file that contains sequence reads and sequence id file that needed to be removed from the fasta file. I have done this earlier, but since id contains a space my piece of code is not working and I don't know how to change it since I'm still learning. fasta file looks like this.

IDList file is like this.

I need to remove these sequences from that fasta file. I have a code I used earlier. But it is not working since id contains a space (I think). Previous code is like this.
# use as follows
# ./filter_seq.bash &lt;fastafile&gt; &lt;list_of_ids_you_want_to_remove&gt;
# ./filter_seq.bash all.fasta bacterial_IDlist

grep &quot;&gt;&quot; $1 | sed 's/&gt;//g' | sort | uniq &gt; all_del
sort $2 | uniq &gt; query_del
comm -23 all_del query_del | sort | uniq &gt; filtered_del
perl -ne 'if(/^&gt;(\S+)/){$c=$i{$1}}$c?print:chomp;$i{$_}=1 if @ARGV' filtered_del $1 &gt; filtered.fasta
rm *_del

I would be grateful if someone can help me.
Install (pip) biopython if u don't have it.
from Bio import SeqIO
with open('/path/ids.txt', 'r') as fin:
    to_keep = set([])
    for line in fin:
        to_keep.add(line.strip().split(' ')[0])
with open('/path/output.fa', 'w') as fout:
    for record in SeqIO.parse('/path/sequences.fa','fasta'):
        if record.id in to_keep:
            SeqIO.write(record, fout, 'fasta')
