Я получаю следующую ошибку при попытке создать DataFrame из моего объекта JSON / Dict. Я довольно плохо знаком с Python и выполняю учебное упражнение, поэтому всякая помощь приветствуется.
Реальная проблема в том, что я хочу 1 ROW (значения) с 100 столбцами, но это говорит мне, что так, как яя установил это, ожидая 100 значений 100 столбцов.
Я смогу сделать эту работу, если не предоставлю columns = json_input.keys (), но по умолчанию это 100 строк против 100 столбцов и1 ряд.
import pandas as pd
json_input = {"x0": "9.521496806", "x1": "wed", "x2": "-5.087588682", "x3": "-17.21471427", "x4": "-2.486421073", "x5": "35.48653879", "x6": "-1.20495816", "x7": "-23.7174973", "x8": "105.7946327", "x9": "-5.951938559", "x10": "5.214871257", "x11": "0.303798139", "x12": "$296.43 ", "x13": "-0.194132881", "x14": "-2.188915191", "x15": "15.8504554", "x16": "-7.419140411", "x17": "6.931577729", "x18": "-33.76908811", "x19": "-1.932735617", "x20": "0.066503478", "x21": "0.014625357", "x22": "-2.826542568", "x23": "-9.51560375", "x24": "27.31797115", "x25": "-4.210150941", "x26": "-13.45071138", "x27": "17.51376958", "x28": "0.14235993", "x29": "6.49488499", "x30": "8.922856241", "x31": "1.264469019", "x32": "-14.22456453", "x33": "-22.51356894", "x34": "2.042085808", "x35": "7.996513763", "x36": "15.62250736", "x37": "-36.34086747", "x38": "2.665399772", "x39": "-1.354001761", "x40": "33.71068143", "x41": "11.74949803", "x42": "-2.793416547", "x43": "71.4392679", "x44": "-3.57085601", "x45": "-10.61019691", "x46": "63.36622572", "x47": "1.084953519", "x48": "0.965175942", "x49": "15.41097088", "x50": "38.02325393", "x51": "-4.601041878", "x52": "9.544564428", "x53": "5.171864325", "x54": "Aug", "x55": "3.238851899", "x56": "-1.444656373", "x57": "-24.85405723", "x58": "-0.127639937", "x59": "14.69515683", "x60": "-3.577237241", "x61": "12.67485", "x62": "-26.60833996", "x63": "22.3566647", "x64": "0.187033314", "x65": "-20.08925727", "x66": "0.3013055", "x67": "9.782791255", "x68": "-0.590871745", "x69": "-27.03617115", "x70": "0.178891203", "x71": "9.297257064", "x72": "-0.687360237", "x73": "23.1353161", "x74": "-1.692361883", "x75": "6.007302227", "x76": "-0.05636968", "x77": "20.23959571", "x78": "4.889493523", "x79": "0.02%", "x80": "20.11423271", "x81": "22.31711274", "x82": "asia", "x83": "-0.072090104", "x84": "volkswagon", "x85": "-0.14252212", "x86": "0.464293542", "x87": "-0.974325314", "x88": "7.131219017", "x89": "-2.506897555", "x90": "-0.069832619", "x91": "-11.84213839", "x92": "0.09761061", "x93": "15.27673142", "x94": "-1.927285625", "x95": "8.008175145", "x96": "0.659805361", "x97": "2.216918955", "x98": "-18.64465705", "x99\n": "-1.926577376"}
