The third constructor takes the string of characters "100" and creates an integer in base 10 (the familiar decimal system).

第三个构造函数采用了字符串“100”并创建了以10为基数的整数值(常见的十进制系统)。

Python supports string literals of integers of different bases-octal, decimal (obviously!), and hexadecimal-and now binary has been added.

Python支持不同进制的整型字符串文本—八进制、十进制(最明显的！)

One takes a double-precision floating point as input, another takes an integer and a scale factor, and another takes a String representation of a decimal number.

其中一个构造函数以双精度浮点数作为输入，另一个以整数和换算因子作为输入，还有一个以小数的String表示作为输入。

And there's probably more digits after the decimal place, but because of my formatting string, I only see a couple of them.

这里可能有更多的小数位，但因为我对结果设定了格式，我们只看到两位。
