PyQt5讀寫文件

一、讀寫txt文件，指定文件數據類型

def my_open(self):
    my_file_path = QFileDialog.getOpenFileName(None, '選擇文件', r'C:\Users\Administrator\Desktop','Excel files(*.txt)')
    with open(my_file_path[0]) as f:
        my_file = f.read()
    self.textEdit.setText(my_file)

def my_save(self):
    my_data = self.textEdit.toPlainText()
    my_file = QFileDialog.getSaveFileName(None,'文件保存',r'C:\Users\Administrator\Desktop','Excel files(*.txt)')
    fs = open(my_file[0],'a+')
    fs.write(my_data)
    fs.close()

二、讀取Word文件：

 def my_open(self):
        from win32com import client as wc
        word = wc.Dispatch('Word.Application')
        # 不打開word程序
        word.Visible = 0
        my_file_path = QFileDialog.getOpenFileName(None, '選擇文件', r'C:\Users\Administrator\Desktop',"word文件(*.docx , *.doc))")
        myworddoc = word.Documents.Open(my_file_path[0])
        #獲取有多少段落
        my_count = myworddoc.Paragraphs.Count
        #循環取出段落，顯示到顯示框中
        for i in range(my_count):
            my_pr = myworddoc.Paragraphs[i].Range
            self.textEdit.append(my_pr.text)
        myworddoc.Close()

　　或者是：

    def my_open(self):
        import docx
        my_file_path = QFileDialog.getOpenFileName(None, '選擇文件', r'C:\Users\Administrator\Desktop',"word文件(*.docx , *.doc))")
        doc = docx.Document(my_file_path[0])
        for i in doc.paragraphs:
            self.textEdit.append(i.text)

三、讀取Ecxle文件一樣的操作，方法比較多如xlrd  pandas等等的，不做記錄
