python - for循环多值

问题描述

我的脚本如下：

import xlsxwriter
import subprocess

workbook = xlsxwriter.Workbook('demo.xlsx')
worksheet = workbook.add_worksheet('NMOC')
bold = workbook.add_format({'bold': True})

 # Write some data headers.
worksheet.write('A1', 'RNC', bold)
worksheet.write('B1', 'CELL', bold)
for line in open('/root/Desktop/Scripting/Update_Table/eaw/test.txt'):

alias = line.rstrip("\n").split(';')
print(alias)

# Start from the first cell. Rows and columns are zero indexed.
row = 1
col = 0

for rnc, cell in (alist):
   worksheet.write(row,col,  rnc)
   worksheet.write(row,col + 1, cell)
   row += 1
workbook.close()

我正在使用 python 3.5 版本。这是我得到的错误：

['BSC19', 'TS9001']
['BSC19', 'TS555']
Traceback (most recent call last):
  File "test.py", line 53, in <module>
    for rnc, cell in (alias):
ValueError: too many values to unpack (expected 2)

我的代码有什么问题？

[root@nocjobs eaw]# cat test.txt

BSC19;TS9001
BSC19;TS555

解决方案

我敢打赌问题就在这里->for rnc, cell in (alist):

因为在某些迭代中（甚至可能是第一次） varalist仅包含一个值，但您尝试将其解压缩为tuple(rnc, cell).

据我了解，你想做这样的事情：

row = 1
for line in open('test.txt'):
    alist = line.rstrip("\n").split(';')
    col = 0
    for value in (alist):
        worksheet.write(row, col, value)
        col += 1
    row += 1
