a boot symbol must be added. 0b for binary, 0o for octal, 0x for hexadecimal, and either case. The theoretical range of integer types is from negative infinity to positive infinity. The actual value is limited by the amount of computer memory...
by passing special floating-point value identifiers, it is possible to create special floating-point values such as NaN (Not a Number) and positive/negative infinity.
特殊浮点数: float('nan'), float('Infinity'), float('-inf')是三个特殊的浮点数,分别代表 非数字(Not a number),无穷大(Infinity), 负无穷大(Negative Infinity) 可以使用标准库 math 模块中的 isnan()判断是否为NaN数据,isinf()判断是否为inf或-inf数据 复数(complex): complex(re, im): re为real,...
If ``indent`` is a non-negative integer, then JSON array elements and object members will be pretty-printed with that indent level. An indent level of 0 will only insert newlines. ``None`` is the most compact representation. If specified, ``separators`` should be an ``(item_separator,...
