这个取决你的业务场景和操作系统,在Python里,把str转换成int,默认是10进制的。 1 2 3 4 5 6 7 8 9 10 >>> int('11') 11 >>> int('11', base=10) # 10 is already default 11 >>> int('11', base=2) # Binary 3 >>> int('11', base=8) # Octal 9 >>> int('11', base=16)...
The IntToStr method accepts an integer value and returns a string holding its decimal representation. Integer values can be decimal, octal or hexadecimal, but the resulting string is always decimal. To convert floating-point numbers, use the FloatToStr or Format method. The FloatToStr method is...
Equivalent to x**y (with two arguments) or x**y % z (with three arguments) Some types, such as ints, are able to use a more efficient algorithm when invoked using the three argument form. """ pass def print(self, *args, sep=' ', end='\n', file=None): # known special case...
int([x[, base]]) 将一个字符转换为int类型,base表示进制 long([x[, base]]) 将一个字符转换为long类型 pow(x, y[, z]) 返回x的y次幂 range([start], stop[, step]) 产生一个序列,默认从0开始 round(x[, n]) 四舍五入 sum(iterable[, start]) 对集合求和 oct(x) 将一个数字转化为8进制...
第一个参数是一串数字,而第二个参数确定数字系统的基数。与二进制文字不同,字符串可以来自任何地方,甚至是用户在键盘上打字。要更深入地了解int(),您可以展开下面的框。 的其他用途 int()显示隐藏 到现在为止还挺好。但是负数呢? 模拟符号位 当你调用bin()一个负整数时,它只是在从相应的正值获得的位串前面加...
alive when the interpreter exits, so__del__can't serve as a replacement for good coding practices (like always closing a connection when you're done with it. In fact,__del__should almost never be used because of the precarious circumstances under which it is called; use it with caution...
You can get the time in seconds using time.time function(as a floating point value). To convert it to milliseconds, you need to multiply it with 1000 and round it off. For example, import time milliseconds = int(round(time.time() * 1000)) print(milliseconds) ...
