Pandas库10_存取json和excel文件

#json文件：javascript object notation
import numpy as np
import pandas as pd

t_data={
"name":["唐浩","小王","老王","赵三","李四","王姐"],
"sex":["男","女","男","女","男","女"],
"year":[37,22,15,18,33,25],
"city":["成都","北京","上海","成都","深圳","北京"]
}

#读取json文件有两种方法
# 方法一：
# fj=open("json_data.json",encoding="utf-8")
# obj=fj.read()
# re=json.loads(obj)
# print(re)
# df=pd.DataFrame(re)
# print(df)

# 方法二：read_json()直接来，比上面要简单一些吧
# df_j=pd.read_json(open("json_data.json",encoding="utf-8"))
# print(df_j)
# #重新排序
# df_j.sort_index()
# print(df_j)

#to_json()函数对json数据进行存储,中文字符是编码了的，待解决
# df_j.to_json(open("json_data7.json","w",encoding="utf-8"),)

#Excel数据的读取与存储，，总结，要安装两个模块：xlrd,openpyxl,不然要报错，
#一、读取：read_excel(),开始要报错，没安装xlrd这个东西，安装后就行了。sheet_name=0第一个工作表，或“Sheet1”
# pd_r_excel=pd.read_excel("123.xlsx",sheet_name="Sheet1")
# print(pd_r_excel)
#二、存储：to_excel()
df_r_t_data=pd.DataFrame(t_data)
print(df_r_t_data)
df_r_t_data.to_excel("23456.xlsx",index=False) #openpyxl要安装这个模块，后就不报错了，
