怎麽用python讀取csv數據

這兩天剛好看到，Python CookBook上有說到。這裏是三種讀取csv的方法。

文件格式是這樣的

Region,DATE_,RAW_ACU

from?collections?import?namedtuple

#?with?open('data.csv')?as?f:

#?f_csv?=?csv.reader(f)

#?headers?=?next(f_csv)

#?for?row?in?f_csv:

#?#?print(row)

#?print(row[0],?row[1])

#?with?open('data.csv',?encoding='utf-8-sig')?as?f:

#?f_csv?=?csv.reader(f)

#?headers?=?next(f_csv)

#?print(headers)

#?Row?=?namedtuple('Row',?headers)

#?for?r?in?f_csv:

#?row?=?Row(*r)

#?print(row.Region,?row.DATE_)

with?open('data.csv',?encoding='utf-8-sig')?as?f:

f_csv?=?csv.DictReader(f)

for?row?in?f_csv:

print(row['DATE_'],?row)
