I’m an absolute beginner with python, and I want to use it mainly for producing 2D plots with matplotlib starting from excel data.
Let’s suppose I have an excel sheet with the numbers 10, 20, 30, 40 in the first four rows of the first column; I want to create a python list with these numbers.
I was trying:
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
['number:10.0', 'number:20.0', 'number:30.0', 'number:40.0']
how can I do, instead, to get something like
['10.0', '20.0', '30.0', '40.0']
so that it is recognized as a list of pure numbers? Is there a way for doing it still using xlrd?
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
Particularly, you want the
will provide the value in the cell.
