小编use*_*350的帖子

我试图在ipython中运行这个文件时不断出现不同的属性错误...大熊猫的初学者所以也许我错过了什么

码:

from pandas import Series, DataFrame

import pandas as pd

import json

nan=float('NaN')
data = []
with open('file.json') as f:
for line in f:
    data.append(json.loads(line))

df = DataFrame(data, columns=['accepted', 'user', 'object', 'response'])
clean = df.replace('NULL', nan)
clean = clean.dropna()

print clean.value_counts() 

AttributeError: 'DataFrame' object has no attribute 'value_counts'

有任何想法吗？
