CSV文件格式 将数据作为一系列以逗号分隔的值 （CSV）
(1). 分析CSV文件头
import csv
filename =
'111.csv'
with open(filename)
as f:
reader = csv.reader(f)
header_row = next(reader)
print(header_row)
(2). 打印文件头及其位置
import csv
filename =
'111.csv'
with open(filename)
as f:
reader = csv.reader(f)
header_row = next(reader)
for index, column_header
in enumerate(header_row):
print(index, column_header)
(3). 提取并读取数据
import csv
filename =
'111.csv'
with open(filename)
as f:
reader = csv.reader(f)
header_row = next(reader)
highs = []
for row
in reader:
highs.append(row[
