读取json文件返回ValueError：期望的对象或值

Question

I'm tried to read a simple json file into pandas (I'm using python 3.7).

%matplotlib inline
import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
data='D:\myfile.json'
pd.read_json(data,orient='columns')

That return ValueError: Expected object or value

please how can I resolve this error to read my json file ? Thank you

Answer 1

Your above code works only for URL that renders a json file. For example,

url = 'https://raw.githubusercontent.com/chrisalbon/simulated_datasets/master/data.json'
df = pd.read_json(url, orient='columns')
df.head(10)

If you want to use your local json file, you have to load it first using with open as below

with open('D:\myfile.json') as data:
    pd.read_json(data,orient='columns')
