Tab-Separated Value library for Python
pip install tsv
TSV files look like this:
# This is an example TSV file
# It lists whether various genes are good or not.
# Sometimes there are column headers that look like comments; we just ignore those.
# GENE STATUS POINTS DATA
BRCA1 GOOD 37
BRCA2 NOT_GOOD -100 c=5
HLA-A VERY_GOOD 3 0,2,3,1,3,2
To read a TSV file, use a TsvReader:
import tsv
reader = tsv.TsvReader(open("file.tsv"))
for parts in reader:
# Here parts is a list of strings, one per tab-separated column.
# Make sure you handle not having enough fields, or not being able to
# parse numbers where you expect them.
print("Record with {} fields: {}".format(len(parts), parts))
To write a TSV file, use a TsvWriter:
import tsv
writer = tsv.TsvWriter(open("file.tsv", "w"))
writer.comment("This is a comment")
writer.line("Column 1", "Column 2", 12345)
writer.list_line(["Column 1", "Column 2"] + list(range(10)))
writer.close()
Since TSV makes no provision for escaping tabs or newlines, users must not provide them within field values.
