[英]Import lists of numbers in python from excel sheets with xlrd
I'm an absolute beginner with python, and I want to use it mainly for producing 2D plots with matplotlib starting from excel data. 我是python的绝对初学者,我想主要用于从excel数据开始使用matplotlib生成2D绘图。
Let's suppose I have an excel sheet with the numbers 10, 20, 30, 40 in the first four rows of the first column; 假设我在第一列的前四行中有一个excel表,其中包含数字10,20,30,40; I want to create a python list with these numbers.
我想用这些数字创建一个python列表。
I was trying: 我在努力:
from xlrd import open_workbook
book = open_workbook('filepathname')
sheet = book.sheet_by_index(0)
list = []
for row in range(0,4):
list.append(str(sheet.cell(row,0)))
in order to create a list with such values... but when I try to print it, I get 为了创建一个具有这些值的列表...但是当我尝试打印它时,我得到了
['number:10.0', 'number:20.0', 'number:30.0', 'number:40.0']
how can I do, instead, to get something like 相反,我怎么能做到这样的事情
['10.0', '20.0', '30.0', '40.0']
so that it is recognized as a list of pure numbers? 这样它被认为是一个纯数列表? Is there a way for doing it still using xlrd?
有没有办法让它仍然使用xlrd?
How about 怎么样
from xlrd import open_workbook
book = open_workbook('filepathname')
sheet = book.sheet_by_index(0)
list = []
for row in range(0,4):
# Remove str(...) if you want the values as floats.
list.append(str(sheet.cell(row,0).value)) # Changed this line
Reference: https://pythonhosted.org/xlrd3/cell.html 参考: https : //pythonhosted.org/xlrd3/cell.html
Particularly, you want the Cell.value
property. 特别是,您需要
Cell.value
属性。
sheet.cell(row, col).value
将提供单元格中的值。
