Python讀取excel,csv數據到數組

numpy中的普通讀取:

import numpy as np
#skiprows可以跳過前幾行數據，np.loadtxt方法直接將數據讀取到data數組中
data = np.loadtxt(open("路徑.csv","rb"),delimiter=",",skiprows=0)

 

讀取Excel:

from openpyxl import load_workbook
#讀取路徑
book = load_workbook(filename=r"路徑.xlsx")
#讀取名字為Sheet1的表
sheet = book.get_sheet_by_name("Sheet1")
#用於存儲數據的數組
data= []
row_num = 1
while row_num <= 100 :
    #將表中第一列的1-100行數據寫入data數組中
    data.append(sheet.cell(row=row_num, column=1).value)
    row_num = row_num + 1
