这里的0b前缀表示这是一个二进制数,如果我们想要去掉这个前缀,可以使用字符串切片: binary_num_without_prefix = binary_num[2:] print(binary_num_without_prefix) # 输出 '1010' 我们还可以手动将一个整数转换为二进制字符串,方法是使用除以2的余数作为二进制位: def int_to_binary(num): binary_str = '...
在得到二进制字符串后,我们可能希望从中提取实际的二进制数。可以通过切片操作去除开头的'0b',像这样: defint_to_binary_without_prefix(num):returnbin(num)[2:]# 测试number=10binary_str_without_prefix=int_to_binary_without_prefix(number)print(f"{number}的二进制表示为:{binary_str_without_prefix}"...
在Python2中,可以通过在字符串前面添加0b来表示二进制数。修改代码如下所示: binary_num='0b10101'# 以0b开头的二进制数字符串decimal_num=int(binary_num,2)# 指定进制为2print(decimal_num)# 输出: 21 1. 2. 3. 在上面的代码中,我们通过将二进制数字符串'0b10101'传递给int()函数,并指定进制为2...

现在我们正在为add、subtract、multiply和divide做我们自己的数学函数。需要注意的重要一点是我们说的最后一行return a + b(在add中)。这样做的效果如下: 我们的函数被调用时带有两个参数:a和b。 我们打印出我们的函数正在做的事情,在这种情况下是“ADDING”。
