将 Python 代码块转换为一行

Question

下面是python块代码，

def compute_hcf(x, y):
   while(y):
       x, y = y, x % y
   return x

我想将其转换为如下所示的单行，

def compute_hcf(x, y):\n\t while(y): \n\t\t x, y = y, x % y \n\t return x

我有以下方法来解决这个问题，

def convert(fname):
    newLines = ''
    with open(fname, 'r') as f:
        for line in f:
            num_spaces = 0
            
            for letter in line:
                if letter != ' ':
                    break
                num_spaces += 1

            if num_spaces == 3:
                line = line.replace(' '*3, '\\t') #If number of Spaces is 3, replace with a single tab
            elif num_spaces == 4:
                line = line.replace(' '*4, '\\t') #If number of Spaces is 4, replace with a single tab
            elif num_spaces == 7:
                line = line.replace(' ' *7, '\\t\\t') #If number of Spaces is 7, replace with double tab
            elif num_spaces == 8:
                line = line.replace(' ' * 8, '\\t\\t') #If number of Spaces is 8, replace with double tab
            line = line + '\\n' #Adding new line at the end of the line
            newLines = newLines + line
    converted = ''.join(newLines)
    print(converted)
    
convert('fileWithInputContent.txt')

实际输出：

def compute_hcf(x, y):
\n\twhile(y):
\n\t\tx, y = y, x % y
\n\treturn x\n

预期输出：

def compute_hcf(x, y):\n\t while(y): \n\t\t x, y = y, x % y \n\t return x
