__init__() 接受 1 到 6 个位置参数，但给出了 20 个

Question

我已从网站提取结果，结果格式如下，适用于其他 93 个计划。我已经创建了一个数据框来存储这些信息，稍后会将这个数据框导出到 csv 文件。但是，我遇到了错误

Traceback (most recent call last):
  File "C:/Study/Web_Crawl/Test_WebC.py", line 104, in <module>
    df = pandas.DataFrame('Snapshot Date', 'URL', 'planId', 'postcode', 'tariffType', 'planName', 'retailerName',
TypeError: __init__() takes from 1 to 6 positional arguments but 20 were given

---

df = pandas.DataFrame('Snapshot Date', 'URL', 'planId', 'postcode', 'tariffType', 'planName', 'retailerName',
                      'retailerCode', 'state', 'effectiveDate', 'solarFit', 'discount', 'dailySupplyCharge',
                    'Controlled Load 1', 'Controlled Load 2', 'Single Rate', 'Off-Peak', 'Peak', 'Shoulder')

Answer 1

你用错了参数，下面是函数签名，来自(link)

class pandas.DataFrame(data=None, index=None, columns=None, dtype=None, copy=False)

数据在哪里

ndarray（结构化或同构）、Iterable、dict 或 DataFrame

所以你应该这样做：

data_array = ['Snapshot Date', 'URL', 'planId', 'postcode', 'tariffType', 'planName', 'retailerName',
                      'retailerCode', 'state', 'effectiveDate', 'solarFit', 'discount', 'dailySupplyCharge',
                    'Controlled Load 1', 'Controlled Load 2', 'Single Rate', 'Off-Peak', 'Peak', 'Shoulder']


df = pandas.DataFrame(data=data_array)
