Python读取excel,csv数据到数组

numpy中的普通读取:

import numpy as np
#skiprows可以跳过前几行数据，np.loadtxt方法直接将数据读取到data数组中
data = np.loadtxt(open("路径.csv","rb"),delimiter=",",skiprows=0)

 

读取Excel:

from openpyxl import load_workbook
#读取路径
book = load_workbook(filename=r"路径.xlsx")
#读取名字为Sheet1的表
sheet = book.get_sheet_by_name("Sheet1")
#用于存储数据的数组
data= []
row_num = 1
while row_num <= 100 :
    #将表中第一列的1-100行数据写入data数组中
    data.append(sheet.cell(row=row_num, column=1).value)
    row_num = row_num + 1
