在python的Pyexcel中遍歷工作表

Question

我想遍歷Excel的所有非空工作表以獲取標題。 我必須為此使用PyExcel。這是我的代碼：

import pyexcel as pe
book = pe.get_book(file_name="Mydata.xlsx")




j=0
print(j)
for j in range(100):
    for item in book.sheet_by_index(j):

     sheet = pe.get_sheet(file_name="Mydata.xlsx")
     sheetheaders= sheet.row_at(0)
     header_list = [i for i in sheetheaders if i != '' ]

     print(header_list)
     j=j+1

誰能告訴我如何迭代而不會出現以下錯誤來幫助我？

Traceback (most recent call last):
   line 11, in <module>
    for sheet in book[i]:
TypeError: 'NoneType' object is not iterable

謝謝！

Answer 1

您不需要在for循環中手動增加索引。 嘗試以下代碼：

for sheet_index in range(book.number_of_sheets()):
    sheet = book.sheet_by_index(sheet_index)
    header_list = [header for header in sheet.row_at(0)]

    print(header_list)

Answer 2

請嘗試以下方法：

import pyexcel as p

header_list = [[ a_header for a_header in sheet.row[0] if a_header] for sheet in p.get_book(file_name="my file.xlsx") if sheet.number_of_rows() > 0]
