打开，编辑和保存Excel

Question

我想打开一个excel文件并编辑该文件。编辑后，我要保存文件。请查看下面的最新进展。不幸的是我得到一个错误。我不知道为什么您能否告诉我该错误并帮助我解决该错误？预先感谢您的支持。期待阅读您的答案。

import openpyxl as oxl

path = '///My Documents/Python/'
fileName = "test.xlsx"    

# name of files to read from
r_filenameXLSX = path+fileName

# open the Excel file
xlsx_wb = oxl.load_workbook(filename=r_filenameXLSX)

# names of all the sheets in the workbook
sheets = xlsx_wb.get_sheet_names()

# extract the worksheet
xlsx_ws = xlsx_wb[sheets[0]]

labels = [cell.value for cell in xlsx_ws.rows[0]]

data = []  # list to hold the data

for row in xlsx_ws.rows[1:]:
    data.append([cell.value for cell in row])


print([item[labels.index('Content')] for item in data[0:10]]) 

错误消息：

C:/Users/user/PycharmProjects/Test/Main.py:29: DeprecationWarning: Call to deprecated function get_sheet_names (Use wb.sheetnames).
  sheets = xlsx_wb.get_sheet_names()
Traceback (most recent call last):
  File "C:/Users/user/PycharmProjects/Test/Main.py", line 34, in <module>
    labels = [cell.value for cell in xlsx_ws.rows[0]]
TypeError: 'generator' object is not subscriptable

Answer 1

[ws.rows是一个生成器，因此您无法进行迭代，可以在该生成器上调用next（）以获取值，

否则请按以下方式使用

wb = oxl.load_workbook(filename=r_filenameXLSX)
ws = wb[wb.sheetnames[0]]

labels = [cell.value for cell in next(ws.rows)]
print(labels)

# 'data' contains data starting from second row 
data = [[ws.cell(i,j).value for j in range(1, ws.max_column+1)] for i in range(2, ws.max_row+1)]

print([item[labels.index('Content')] for item in data[0:10]]) 

将Excel工作表加载到表的最佳方法是使用pandas.read_excel

import pandas as pd
df = pd.read_excel(r_filenameXLSX, sheet_name='your_sheet_name_here')
print(df['Content'])
