我正在嘗試在csv中編寫函數(shù)的結(jié)果。不幸的是，沒有熊貓。csv文件輸入：Hello all well?today is cold!I have not had lunch yetHe does not have many brothers or sisters.We are sick腳本：import reimport csvimport stringwith open('teste_csv.csv', 'r') as f: file = csv.reader(f) for line in file: message = ''.join(line) def toto(message): message = message.lower() p = re.compile('|'.join(map(re.escape, string.punctuation))) no_punct = p.sub(' ', message) writer = csv.writer(open('result.csv', 'w')) for row in no_punct: writer.writerow(row) return writer print(toto(message))在終端上，我有<_csv.writer對象，位于0x7fee60e57c50>，在result.csv中，我只有一行寫為'w'。我希望每一行都在我的result.csv中

您需要將編寫器放在第一個(gè)循環(huán)之外。每次循環(huán)拋出時(shí)，它都會打開并重寫文件
您正在定義另一個(gè)問題，并在循環(huán)內(nèi)調(diào)用toto，以便使用最后一個(gè)消息值來調(diào)用它。
import re
import csv
import string
with open('test.csv', 'r') as f:
file = csv.reader(f)
writer = csv.writer(open('result.csv', 'w'))
def toto(message):
message = message.lower()
p = re.compile('|'.join(map(re.escape, string.punctuation)))
no_punct = p.sub(' ', message)
for row in no_punct:
writer.writerow(row)
return writer
for line in file:
print line
message=''.join(line)
print(toto(message))
