Python将Counter结果输出保存到csv文件
from collections import Counter
import csv
recounted = Counter(M) #M为待统计数组
dict(recounted) #转换为字典
header=['r-num','count'] #csv列名
with open('test.csv','w',newline='')as f:
writer=csv.writer(f)
writer.writerow(header)
for key,value in recounted.items():
writer.writerow([key,value])
