PyQt學習筆記 開啟檔案並從中讀取資料（高階篇）

1 本文實現了開啟 txt、word、excel 格式檔案

2 讀取檔案內容

3 並列印到text.browser上

import docx

from xlrd import open_workbook
@pyqtslot(
)def
on_menu_files_open_triggered
(self)
:## win32com 對python3.x 支援效果不好，棄用之
# from win32com import client as wc
# word.visible = 0
print
("開啟"
)        dialog = qfiledialog(
)        my_file_path = dialog.getopenfilename(self,
"開啟檔案"
,"e:\\7program\\pycharm\\pyqt\\eric6-19.03\\workspace\\")[
0]print
(my_file_path)
if my_file_path[-4
:]=='.doc'
or my_file_path[-5
:]=='.docx'
:# my_worddoc = word.documents.open(my_file_path.replace('/', '\\'))
# print(type(my_worddoc))
# my_count = my_worddoc.paragraph.count
# for i in range(my_count):
#     my_pr = my_worddoc.paragraph[i].range
#     print(my_pr.text)
# my_worddoc.close()
## 採用 python-docx
# my_doc = docx.document(my_file_path.replace('/', '\\'))
# # print(my_doc.paragraphs[0].text)
# for my_paragraph in my_doc.paragraphs:
#     print(my_paragraph.text)
'/',
'\\'))
)elif my_file_path.endswith(
'.xlsx'):
print
('excel!'
)            wb = open_workbook(my_file_path.replace(
'/',
'\\'))
for s in wb.sheets():
for row in
range
(s.nrows)
:for col in
range
(s.ncols)
:print
(s.cell(row, col)
.value)
elif my_file_path[-4
:]=='.txt'
:            f =
open
(my_file_path[0]
,'r'
, encoding=
"utf-8"
)            my_data = f.read(
)            f.close(
)else
:            qmessagebox.information(self,
'information'
,'不支援的檔案格式'
)

2 encoding

3 path "/" 轉義

4 cell 類的用法
