csv文件内容如下：
1 Twin Oaks Place 10 Marquette Rd. 12 Craven Way 12 Fort Sheriden Ave. 12 Skokie Valley Rd. 12 Walker Ave. 120 high St.
一、使用内置函数处理
计算
安全
数据库
网络和加速
企业服务
# /usr/bin/env python
# -*- coding:utf-8 -*-
import sys
import json
reload(sys)
sys.setdefaultencoding('utf-8')
#根据列表中是否为空，将不为空的配成键值对更新到字典中
def list_name(keyname, value1, dict1=None):
dict1 = dict(zip(keyname, value1))
return dict1
with open(r'D:\address.csv', 'rb') as f:
for line in f:
if line == []:
line =""
else:
if line[-1] == "\n":
line = line[:-1]
if line[-1] == "\r":
line = line[:-1]
akk = [y for y in line.split(" ")]
key1 = ['street','namefirst','namelast','address']
a1 = {}
arr = list_name(key1,akk,a1)
arr = json.dumps(arr)
print arr输出如下：
{"namelast": "Oaks", "street": "1", "namefirst": "Twin", "address": "Place"}
{"namelast": "Rd.", "street": "10", "namefirst": "Marquette"}
{"namelast": "Way", "street": "12", "namefirst": "Craven"}
{"namelast": "Sheriden", "street": "12", "namefirst": "Fort", "address": "Ave."}
{"namelast": "Valley", "street": "12", "namefirst": "Skokie", "address": "Rd."}
{"namelast": "Ave.", "street": "12", "namefirst": "Walker"}
{"namelast": "St.", "street": "120", "namefirst": "high"}二、自己定义函数，内容可控
# /usr/bin/env python
# -*- coding:utf-8 -*-
import sys
import json
reload(sys)
sys.setdefaultencoding('utf-8')
#根据列表中是否为空，将不为空的配成键值对更新到字典中
def list_name(keyname, value1, dict1=None):
for i in range(0, len(value1)):
if value1[i] == "":
break
else:
dit = {keyname[i]: value1[i]}
dict1.update(dit)
i += 1;
return dict1
with open(r'D:\address.csv', 'rb') as f:
for line in f:
if line == []:
line =""
else:
if line[-1] == "\n":
line = line[:-1]
if line[-1] == "\r":
line = line[:-1]
akk = [y for y in line.split(" ")]
key1 = ['street','namefirst','namelast','address']
a1 = {}
arr = list_name(key1,akk,a1)
arr = json.dumps(arr)
print arr输出如下：
{"namelast": "Oaks", "street": "1", "namefirst": "Twin", "address": "Place"}
{"namelast": "Rd.", "street": "10", "namefirst": "Marquette"}
{"namelast": "Way", "street": "12", "namefirst": "Craven"}
{"namelast": "Sheriden", "street": "12", "namefirst": "Fort", "address": "Ave."}
{"namelast": "Valley", "street": "12", "namefirst": "Skokie", "address": "Rd."}
{"namelast": "Ave.", "street": "12", "namefirst": "Walker"}
{"namelast": "St.", "street": "120", "namefirst": "high"}到此，关于“Python怎么将csv格式转换成JSON格式文件”的学习就结束了，希望能够解决大家的疑惑。理论与实践的搭配能更好的帮助大家学习，快去试试吧！若想继续学习更多相关知识，请继续关注亿速云网站，小编会继续努力为大家带来更多实用的文章！
