在Python中,print函数的flush参数用于控制输出缓冲区的刷新。 当flush参数为True时,会强制刷新缓冲区并立即将输出内容显示在屏幕上 当flush参数为False(默认值)时,输出内容会被缓冲,只有在缓冲区已满或程序结束时才会被刷新并显示出来 >>> import time >>> >>> for num in range(10): ... print(num, end...
print handles bytes and other types by calling their string representation methods. Best PracticesUse f-strings: For clean, readable string formatting (Python 3.6+) Consider end parameter: For progress indicators without newlines Implement __str__: For custom objects to print meaningfully Use file ...
