Python3 print()函数sep,end,file参数用法练习

来自builtins.py：
def print(self, *args, sep=' ', end='
', file=None): # known special case of print
    """
    print(value, ..., sep=' ', end='
', file=sys.stdout, flush=False)
    
    Prints the values to a stream, or to sys.stdout by default.
    Optional keyword arguments:
    file:  a file-like object (stream); defaults to the current sys.stdout.
    sep:   string inserted between values, default a space.
    end:   string appended after the last value, default a newline.
    flush: whether to forcibly flush the stream.
    """
    pass

联系，看着理解。

print('abc','def','ghi
',sep='***',end='**')
print('abc','def','ghi',sep='***',end='**')
print('abc
','def
','ghi',sep='***',end='**')

输出如下：

abc***def***ghi
**abc***def***ghi**abc
***def
***ghi**
