您需要在WebAPI中启用交叉源，如下所示

#!/usr/bin/env python

import subprocess
import os
import csv

#write output in a table with three columns namely filename, Total sequences, Total variants, Percentage of variants 

csvfile = "./" #path to output csv
def print_table(table):
    from tabulate import tabulate
        tabulate(table, headers=["Filename","Total sequences", "Total variants", "Percentage variants/total sequences"])
    print_table(table)


with open('query.txt', 'r') as f:
    for line in f:
        line = line.rstrip() # remove trailing whitespace such as '\n'
        subprocess.call(['/bin/grep', line, 'my2.txt'])

cat DataID_F(or R).fas | grep -c ">" > Results.csv (total sequences)
cat DataID_F(or R).fas | grep -c "-AAT-T-" > Results.csv (total variants)

from __future__ import division #calculating the percentage variants
