这篇文章主要介绍"Python怎么将csv格式转换成JSON格式文件"，在日常操作中，相信很多人在Python怎么将csv格式转换成JSON格式文件问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答"Python怎么将csv格式转换成JSON格式文件"的疑惑有所帮助！接下来，请跟着小编一起来学习吧！

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

# /usr/bin/env python# -*- coding:utf-8 -*-import sysimport jsonreload(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 dict1with 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 sysimport jsonreload(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 dict1with 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"}
