這篇文章主要介紹“Python怎么將csv格式轉換成JSON格式文件”,在日常操作中,相信很多人在Python怎么將csv格式轉換成JSON格式文件問題上存在疑惑,小編查閱了各式資料,整理出簡單好用的操作方法,希望對大家解答”Python怎么將csv格式轉換成JSON格式文件”的疑惑有所幫助!接下來,請跟著小編一起來學習吧!
csv文件內容如下:
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、使用內置函數處理
# /usr/bin/env python # -*- coding:utf-8 -*- import sys import json reload(sys) sys.setdefaultencoding('utf-8') #根據列表中是否為空,將不為空的配成鍵值對更新到字典中 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,內容可控
# /usr/bin/env python # -*- coding:utf-8 -*- import sys import json reload(sys) sys.setdefaultencoding('utf-8') #根據列表中是否為空,將不為空的配成鍵值對更新到字典中 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"}
