Python 列函数

Question

我想要一个函数，它将通过数据库列的模式创建列。这些创建的列将计算每个观察的模式百分比

Answer 1

首先，您必须将数据加载为 JSON/Array。

import pandas as pd
hold_data = pd.read_csv (r'C:\Users\abdulalim\Desktop\Test\Products.csv')
hold_data.to_json (r'C:\Users\abdulalim\Desktop\Test\New_Products.json')

输出：{"Product":{"0":"Desktop Computer","1":"Tablet","2":"Printer","3":"Laptop"},"Price":{"0":700,"1":250,"2":120,"3":1200}}

如果数据获取为数组：

def get_data(request):
    hold_data = request.data
    for key in hold_data:
        print(key[0])
        print(key[1])

如果数据为 Json:

def get_data(request):
    hold_data = request.data
    hold_data['data1']
    hold_data['data2']

获得数据后，随心所欲
