为什么“\”和“/”是混合的?
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
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(在我看来)
来自os.getcwd()
:J:\
来自QFileDialog
:C:/Users/******/setup.py
这是因为QFileDialog
uses forward slashes regardless of OS. This makes it easier to write path handling code。
您可以使用os.path.normpath
将正斜杠转换为Windows上路径中的反斜杠。
