>>> hex(42) '0x2a' >>> oct(42) '0o52' 请注意十六进制系统如何利用字母A直通F来扩充可用数字集。其他编程语言中的八进制文字通常以纯零作为前缀,这可能会造成混淆。Python 明确禁止此类文字以避免出错: >>> >>> 052 File "", line 1 SyntaxError: leading zeros in decimal integer literals are not...

1. 使用格式化字符串字面值(f-string)*Python3.6之后 格式化字符串字面值或称 f-string 是带有 'f' 或 'F' 前缀的字符串字面值。这种字符串可包含替换字段,即以 {} 标示的部分。{} 之外的部分按照字面值处理。 可替换字段 {} 可以包含: Python表达式 注意:lambda表达式和赋值表达式必须显式地加上圆括号 (...

Let’s take a 32-bit unsigned integer corresponding to the number 196910, which was the year when Monty Python first appeared on TV. With all the leading zeros, it has the following binary representation 000000000000000000000111101100012. How would you store such a value in computer memory? If ...
.as_integer_ratio() Returns a pair of integers whose ratio is exactly equal to the original float .is_integer() Returns True if the float instance is finite with integral value, and False otherwise .hex() Returns a representation of a floating-point number as a hexadecimal string .fromhex(...
