You could use a "dummy value"
ercc_contigs = {}
for line in open('Faq_ERCC_contigs_name.txt'):
gene = line.split()[0]
ercc_contigs[gene] = None
but a better approach is to use a set instead of a dict:
ercc_contigs = set()
for line in open('Faq_ERCC_contigs_name.txt'):
gene = line.split()[0]
ercc_contigs.add(gene)
