今天python操作二进制然后报错,记录一下 >>>int(101,2) Traceback (most recentcalllast): File "<stdin>", line1,in<module>TypeError:int() can't convert non-string with explicit base >>> 问题原因 int() 其实是一个类 classint(x, base=10) ...
python3中的整型只有int,小数只有float。type函数可以用来查看类型。 /表示小数除法,例如2/2=1.0,type(2/2)是float。 //表示整数除法,例如1//2=0,type(1//2)是int。 进制 二进制:在数字前加0b,例如2(0b10)、3(0b11) bin函数将任意进制转换成二进制,bin(10)显示0b1010、bin(0o7) ...
