print(x, y) inserts a default space between x and y . Therefore, the space remains even when x empty. Replace the comma with a + to print as one line: print(x + y) .

for people attracted here by the title of the question - not relevant to the task in the question itself:

You can use s = s.lstrip() to remove all spaces at the beginning of a line:

 >>> ' \na \n'.lstrip() 'a \n'
