1. 使用bin()函数 Python中的bin()函数可以将一个整数转换为二进制字符串。这个函数接受一个整数作为参数,并返回一个以"0b"开头的二进制字符串。下面是一个示例代码: num=10binary=bin(num)print(binary) 1. 2. 3. 上述代码中,将整数10转换为二进制字符串,并将结果打印出来。输出结果为:“0b1010”。可...
windows --> 运行 --> 输入cmd ,然后回车,弹出cmd程序,输入python,如果能进入交互环境 ,代表安装成功。 如果不成功,应该设置环境变量:右击我的电脑—属性,选择高级系统设置—环境变量—找到path 找到python安装文件,前边要加分号,复制粘贴其路径,然后,再复制Scripts的路径加在后边,最后加分号即可,确实,设置成功。 I...

We know what a binary tree is and the terminology connected with it. We will implement the binary tree using Python to understand better how the binary tree works. All we have to do is copy that code here and write new code in it. Because it’s part of the binary tree, we must wri...

print 成为了函数,python2 是关键字 不再有 unicode 对象,默认 str 就是 unicode python3 除号返回浮点数 没有了long类型 xrange 不存在,range 替代了 xrange 可以使用中文定义函数名变量名 高级解包和*解包 限定关键字参数 *后的变量必须加入名字=值
