py把一个数转化成二进制

Sure, I can help you with that! Here's a simple code snippet in Python to convert a number into its binary representation:
```python
num = 42 # your number here
binary = bin(num)
print(binary)
```
This will output: `0b101010`. The `bin()` function converts the number into a binary string, which is prefixed with `0b`.

将用户提供的二进制数转化为十进制数。(选作)具体的调用格式如下: $ ./bin2dec 1001 1001(b) = 9(d) $ ./bin2dec 222 222 is not a valuable binary number.
Python代码实现:
```python
import sys
# 判断输入是否为二进制数
def is_binary(num):
for i in num:
if i != '0' and i != '1':
return False
return True
# 将二进制数转化为十进制数
def bin2dec(num):
res = 0
for i in range(len(num)):
res += int(num[i]) * pow(2, len(num)-i-1)
return res
if __name__ == '__main__':
if len(sys.argv) != 2:
print("Usage: python bin2dec.py [binary number]")
else:
num = sys.argv[1]
if is_binary(num):
print("{}(b) = {}(d)".format(num, bin2dec(num)))
else:
print("{} is not a valuable binary number.".format(num))
```
运行结果:
```
$ python bin2dec.py 1001
1001(b) = 9(d)
$ python bin2dec.py 222
222 is not a valuable binary number.

二进制文件怎么转化成c++语言ubuntu,命令操作
要在Ubuntu命令行中将二进制文件转换为C++源代码,可以使用以下命令:
1. 安装IDA Pro和Ghidra
```
sudo apt-get install ida-pro
sudo apt-get install ghidra
```
2. 使用IDA Pro将二进制文件转换为C++源代码
```
./ida64 -B -S"/usr/share/ida-pro/python/3/elf/cpptocode.py" input_binary
```
其中,`input_binary`是要转换的二进制文件名,`-B`选项表示以批处理模式运行,`-S`选项指定要执行的Python脚本。
3. 使用Ghidra将二进制文件转换为C++源代码
```
ghidraRun /path/to/ghidra/analyzeHeadless /path/to/project /path/to/script -process input_binary
```
其中,`/path/to/ghidra`是Ghidra的安装路径,`/path/to/project`是Ghidra项目文件夹的路径,`/path/to/script`是要执行的Ghidra脚本的路径,`input_binary`是要转换的二进制文件名。
需要注意的是,转换过程可能需要一些技术知识和经验,建议在进行此操作之前先进行必要的学习和准备。
