如何让选择在python中保存csv文件的目录？

Question

我有蟒蛇这个函数创建一个简单的CSV不过outFile，但我想我选择的保存与Windows资源管理器的目录，我的功能：

def exporter(): 
    name_of_file="export" 
    l = [[1, 2], [2, 3], [4, 5]] 
    completeName = os.path.abspath("C:\temp\%s.csv" % name_of_file) 
    out = open(completeName,"w") 
    for row in l: 
     for column in row: 
      out.write('%d;' % column) 
      out.write('\n') 
     out.close() 

    QObject.connect(export, SIGNAL('clicked()'),exporter) 

出口是一个QPushButton，谢谢！

def exporter(directory='C:\temp\\'): 
    name_of_file = "export" 
    l = [[1, 2], [2, 3], [4, 5]] 
    completeName = os.path.abspath("C:/temp/%s.csv" % name_of_file) 
    full_path = '%(directory)s\%(name_of_file)s.csv' % locals() 
    out = open(full_path, "w") 
    for row in l: 
     for column in row: 
      out.write('%d;' % column) 
      out.write('\n') 
     out.close() 

    QObject.connect(export, SIGNAL('clicked()'),exporter) 

像这样的事情会做的。只是通过路径作为参数。
