Ich habe den vorherigen Beitrag geschrieben, um die TOPIX-Zeitreihen anzuzeigen Speichern Sie es in verschiedenen Formaten, um es später einfach zu verarbeiten.
Das Gleiche wie vorher. Ich habe jedoch einen Funktionsaufruf namens "savedataAs irgendwie (Dateiname, Daten)" eingegeben.

savedataAsPickle('topix.pickle', data)
savedataAsCSV('topix.csv', data)
savedataAsExcel('topix.xlsx', data)
pickle Formate in der Standard-Python-Bibliothek
def savedata(filename, data):
pickle.dump(data, open(filename, "w"))
csv Abkürzung für Comma Separated Values. Textformat.
def savedata(filename, data):
import csv
csvobj = csv.writer(open(filename, "w"))
csvobj.writerows(data)
Speichern Sie in einem Format, das von Excel gelesen werden kann
def savedata(filename, data):
import openpyxl.workbook
import openpyxl.cell
wb = openpyxl.workbook.Workbook()
ws = wb.worksheets[0]
ws.title = "TOPIX"
for idat, dat in enumerate(data):
col = openpyxl.cell.get_column_letter(idat + 1) # from 1, 2, ... to A, B, ...
for irow, d in enumerate(dat):
ws.cell('%s%s'%(col, irow + 1)).value = d
wb.save(filename)
