for line in file:print(line)```在上面的代码中，`newline='\n'`表示使用Unix系统中的换行符（`\n`）作为换行符。如果要在Windows系统中使用换行符（`\r\n`），则可以将`newline`设置为`'\r\n'`。此外，还可以在`print()`函数中使用`end`参数来指定换行符。例如：```python print('Hello, world!
3. Print Without a New Line in Python 3.x In Python 3.x, to display without a newline useendparam to theprint()function. This end parameter tells the python runtime to display the string with the next print statement in the same line. With this you can understand that print() statem...
