为什么“\”和“/”混用？

os.getcwd() 发出反斜杠字符串。

另一方面，QFileDialog发出正斜杠字符串。

为什么？

例子

请执行此示例代码。

from PySide import QtGui
from PySide import QtCore
import sys
import os

class DirectoryPrinter(QtGui.QWidget):
    def __init__(self,parent=None):
        super(DirectoryPrinter,self).__init__(parent=None)

        self.filedialog_pushbutton = QtGui.QPushButton("filedialog",self)
        self.connect(self.filedialog_pushbutton,QtCore.SIGNAL("clicked()"),self.filename_getter)

    def filename_getter(self):
        print("from os.getcwd()",os.getcwd())
        filename = QtGui.QFileDialog.getOpenFileName(self,"Select your file",os.path.expanduser("~"))[0]
        print("from QFileDialog",filename)


def main():
    try:
        QtGui.QApplication([])
    except Exception as e:
        print(22,e)
    directoryprinter = DirectoryPrinter()
    directoryprinter.show()

    sys.exit(QtGui.QApplication.exec_())
if __name__ == "__main__":
    main()

结果（在我的场合）

来自os.getcwd()：J:\

来自QFileDialog：C:/Users/******/setup.py

我自己已经解决了这个问题，但是我将这个问题交给其他人解决。我认为这种问题尽可能地好。而且SOF中似乎没有。

我更新spyder和PyQt5。
