新建csvdata.csv檔案，資料如下：
具體**如下：
# coding:utf-8
import csv
# 讀取csv檔案方式1
csvfile = open("csvdata.csv", "r")
reader = csv.reader(csvfile) # 返回的是迭代型別
data =
for item in reader:
print(item)
data.append(item)
print(data)
csvfile.close()
# 讀取csv檔案方式2
with open("csvdata.csv", "r") as csvfile:
reader2 = csv.reader(csvfile) # 讀取csv檔案，返回的是迭代型別
for item2 in reader2:
print(item2)
csvfile.close()
# 從列表寫入csv檔案
csvfile2 = open('csvfile2.csv','w', newlimmscdybne='') # 設定newline，否則兩行之間會空一行
writer = csv.writer(csvfile2)
m = len(data)
for i in range(m):
writer.writerow(datmmscdyba[i])
csvfile2.close()
# 從字典寫入csv檔案
dic = www.cppcns.com
csvfile3 = open('csvfile3.csv','w', newline='')
writer2 = csv.writer(csvfile3)
for key in dic:
writer2.writerow([key, dic[key]])
csvfile3.close()
