如何在python中將文件寫入桌面？

Question

當我將這段代碼寫入一個可執行文件時，寫入文件的功能起作用，但它寫入了一個隨機目錄。我不知道如何讓它寫入我的桌面，就像它是一個普通的python文件時一樣。

這裏是我的代碼，

def write(): 
     print('Creating a new file') 

     name = raw_input('Enter a name for your file: ')+'.txt' # Name of text file coerced with +.txt 

     try: 
      file = open(name,'w') # Trying to create a new file or open one 
      file.close() 

     except: 
      print('Something went wrong! Cannot tell what?') 
      sys.exit(0) # quit Python

您需要指定要保存的路徑。此外，請使用os.path.join（documentation）將路徑和文件名放在一起。你可以這樣做：

from os.path import join 
def write(): 
     print('Creating a new file') 
     path = "this/is/a/path/you/want/to/save/to" 
     name = raw_input('Enter a name for your file: ')+'.txt' # Name of text file coerced with +.txt 

     try: 
      file = open(join(path, name),'w') # Trying to create a new file or open one 
      file.close() 

     except: 
      print('Something went wrong! Cannot tell what?') 
      sys.exit(0) # quit Python

它不寫入隨機目錄。它正在寫入當前目錄，即從中運行它的目錄。如果您希望它寫入特定目錄（如桌面），則需要將路徑添加到文件名或切換當前目錄。首先是與

 
name = os.path.join('C:\Users\YourUser\Desktop', name) 

二是所做的一切與

 
os.chdir('C:\Users\YourUser\Desktop') 

或任何路徑到桌面是。
