Python 如何读取.csv文件的单个列？

Question

如题所述

Answer 1

import xlrd

EXCEL_BOOK_FULLNAME='FULL FILE NAME'

workbook=xlrd.open_workbook(EXCEL_BOOK_FULLNAME)

worksheet=workbook.sheet_by_name('Sheet1')

rows=worksheet.nrows #worksheet rows

cols=worksheet.ncols #worksheet columns

lists=[[],[],[],[]] ＃modify this according your column counts

for c in range(cols): #transfer excel values into lists

for r in range(rows):

lists[c].append(worksheet.cell_value(r,c))追问

请问导入xlrd需要加入什么包吗？
workbook=xlrd.open_workbook(EXCEL_BOOK_FULLNAME)
这句话运行不了
