Python“IndexError：列表索引超出范围”| 目标：读取1个excel文件并将数据追加到第二个excel文件
脚本的目标是从每天从cron作业生成的excel文件中获取数据并将该数据追加到“master”excel文件的底部。
这是我现在的地方：
# Find the most recent excel file created by the cron job & open it. localtime = time.localtime(time.time()) yy = localtime.tm_year mm = localtime.tm_mon dd = localtime.tm_mday file_name = 'daily_' + str(yy) + '_' + str(mm) + '_' + str(dd-1) + '.xls' file_loc = '/Users/' + file_name new_sheet = open_workbook(file_loc, on_demand=True).sheet_by_index(0) # Grab all the data from the recent cron job file starting at row 2 to avoid # including headers. for row in range(1, new_sheet.nrows): values = [] for col in range(new_sheet.ncols): values.append(new_sheet.cell(row,col).value) """ The above loop structures the list 'values[]' in a way that the print statement of value looks like the below output; which matches the formatting of master_file.xlsx: 2341511 Sports 12112 Dog 324.92 71611 Other 18192 Cat 128.17 ... """ # Find the excel master file & open it. sheet = open_workbook('master_file.xlsx').sheet_by_index(0) # Find the first row that is empty. new_row = sheet.nrows + 1 # Append the values[] list to the master file starting at row(new_row) and save # the db file. for row_num, row in enumerate(values, new_row): for col_num, col in enumerate(row): sheet.row(row_num).write(col_num, col) sheet.save('master_file.xlsx') 我的回溯错误是：
File "daily.py", line 45, in <module> sheet.row(row_num).write(col_num, col) File "/Users/code/env/lib/python2.7/site-packages/xlrd/sheet.py", line 462, in row for colx in xrange(len(self._cell_values[rowx])) IndexError: list index out of range
任何帮助将不胜感激！
从代码直觉是你实际上没有添加一行到工作表之前迭代。
xlrd看起来不像它实际上有方法来修改现有的工作表。 看看这个SOpost可能有帮助…
如何使用xlrd将新的列和行添加到.xls文件
你的意思是有col(new_row)而不是col ，如下所示：
for row_num, row in enumerate(values, col(new_row)): for col_num, col(new_row) in enumerate(row): sheet.row(row_num).write(col_num, col(new_row))
