這篇文章主要介紹“Python怎么將csv格式轉(zhuǎn)換成JSON格式文件”,在日常操作中,相信很多人在Python怎么將csv格式轉(zhuǎn)換成JSON格式文件問(wèn)題上存在疑惑,小編查閱了各式資料,整理出簡(jiǎn)單好用的操作方法,希望對(duì)大家解答”P(pán)ython怎么將csv格式轉(zhuǎn)換成JSON格式文件”的疑惑有所幫助!接下來(lái),請(qǐng)跟著小編一起來(lái)學(xué)習(xí)吧!

csv文件內(nèi)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、使用內(nèi)置函數(shù)處理
# /usr/bin/env python
# -*- coding:utf-8 -*-
import sys
import json
reload(sys)
sys.setdefaultencoding('utf-8')
#根據(jù)列表中是否為空,將不為空的配成鍵值對(duì)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輸出如下:
{"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、自己定義函數(shù),內(nèi)容可控
# /usr/bin/env python
# -*- coding:utf-8 -*-
import sys
import json
reload(sys)
sys.setdefaultencoding('utf-8')
#根據(jù)列表中是否為空,將不為空的配成鍵值對(duì)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輸出如下:
{"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,關(guān)于“Python怎么將csv格式轉(zhuǎn)換成JSON格式文件”的學(xué)習(xí)就結(jié)束了,希望能夠解決大家的疑惑。理論與實(shí)踐的搭配能更好的幫助大家學(xué)習(xí),快去試試吧!若想繼續(xù)學(xué)習(xí)更多相關(guān)知識(shí),請(qǐng)繼續(xù)關(guān)注創(chuàng)新互聯(lián)-成都網(wǎng)站建設(shè)公司網(wǎng)站,小編會(huì)繼續(xù)努力為大家?guī)?lái)更多實(shí)用的文章!
