打印成一个文本文件循环

Question

我希望能够打印到一个文本文件，但是我环顾四周，无法弄清楚我需要做什么。

def countdown (n): 
    while (n > 1): 
     print('\n',(n), 'Bottles of beer on the wall,', (n), 'bottles of beer, take one down pass it around', (n)-1, 'bottles of beer on the wall.') 
     n -= 1 
     if (n == 2): 
      print('\n',(n), 'Bottles of beer on the wall,', (n), 'bottles of beer, take one down pass it around', (n)-1, 'bottle of beer on the wall.') 
     else: 
      print ('\n',(n), 'Bottle of beer on the wall,', (n), 'bottle of beer, take one down pass it around no more bottles of beer on the wall.')

Answer 1

而不是...

... 
print('123', '456') 

使用...

myFile = open('123.txt', 'w') 
... 
print('123', '456', file = myFile) 
... 
myFile.close() # Remember this out! 

甚至......

with open('123.txt', 'w') as myFile: 
    print('123', '456', file = myFile) 

# With `with`, you don't have to close the file manually, yay! 

我希望这对导致一些光您！

为了更“正确”，它将被认为写入文本文件。你可以这样编码：

def countdown (n): 
    # Open a file in write mode 
    file = open('file name', 'w') 
    while (n > 1): 
     file.write('\n',(n), 'Bottles of beer on the wall,', (n), 'bottles of beer, take one down pass it around', (n)-1, 'bottles of beer on the wall.') 
     n -= 1 
     if (n == 2): 
      file.write('\n',(n), 'Bottles of beer on the wall,', (n), 'bottles of beer, take one down pass it around', (n)-1, 'bottle of beer on the wall.') 
     else: 
      file.write('\n',(n), 'Bottle of beer on the wall,', (n), 'bottle of beer, take one down pass it around no more bottles of beer on the wall.') 

    # Make sure to close the file, or it might not be written correctly. 
    file.close()
