Whether output is buffered is usually determined byfile, but if theflushkeyword argument is true, the stream is forcibly flushed. Changed in version 3.3: Added theflushkeyword argument. 函数信息表格 print函数的格式化输出 格式化输出: 范例1:基本的打印输出(Python 3.6.2 shell 环境) >>> print(1,'...
几乎每个人刚接触Python时,都会Hello World一下,而把这句话呈现在我们面前的,就是print函数了。help本身也是一个内置函数,我们现在来help一下。 >>> help(print) Help on built-in function print in module builtins: print(...) print(value, ..., sep=' ', end='\n', file=sys.stdout, flush=Fal...
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. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 参数的具体含义如下: value --表示输出的对象。输出多个对象时,需要用 , (逗号...

通常情况下,Python的数据类型的"高低"可以按照如下顺序理解:布尔(bool)< 整型(int) < 浮点型(float)< 复数(complex)。这个顺序主要根据数据类型可以表示的信息范围和精度来确定的。 不同数据类型之间能否随意转化: 虽然Python提供了一些内置的函数来实现不同数据类型之间的转换,如int(), float(), str(), list(...

Return Value from print() One important thing to remember is that Python print() returns no value. It returns None. This is because in Python 2.x, it is considered as a reserved keyword and not a function. Let us now move forward by going through a couple of examples using the Python...
