Python: skip comment lines marked with # in csv.DictReader

Question

Processing CSV files with csv.DictReader is great - but I have CSV files with comment lines in (indicated by a hash at the start of a line), for example:

# step s         


        

Answer 1

Actually this works nicely with filter:

import csv
fp = open('samples.csv')
rdr = csv.DictReader(filter(lambda row: row[0]!='#', fp))
for row in rdr:
    print(row)
fp.close()
