Python3编码转换大全

进制转换

其他进制转十进制

2 -> 10

```python
?1 int(‘1100‘,2) 2 12?
```

8 -> 10

```python
int(‘1100‘,8)
576
```

16 -> 10

```python
int(‘1100’,16)
4352
```

十进制转其他进制

10 -> 2

```python
bin(170)
‘0b10101010‘
```

10 - > 8

```python
oct(170)
‘0o252’
```

10 -> 16

```python
hex(170)
‘0xaa’
```

Html编码

```python
import html
html.unescape(‘&#102‘)
’f‘
```

当然也可以多个字符

```python
import html
html.unescape(‘flag‘)
‘flag‘
```

Base编码

加密

base64

```python
import base64
a=b‘233‘
b=base64.b64encode(a)
b
b‘MjMz‘
```

base32

```python
import base64
a=b‘233‘
b=base64.b32encode(a)
b
b‘GIZTG===‘
```

base16

```python
import base64
a=b‘233‘
b=base64.b16encode(a)
b
b‘323333‘
```

解码

base64

```python
import base64
a=b‘MjMz‘
b=base64.b64encode(a)
b
b‘233‘
```

base32

```python
import base64
a=b‘GIZTG===‘
b=base64.b32decode(a)
b
b‘233‘
```

base16

```python
import base64
a=b‘323333‘
b=base64.b16decode(a)
b
b‘233‘
```

至于base58

这个因为比较晚，所以在另外一个库base58里

编码

```python
import base58
a=b‘233‘
b=base58.b58encode(a)
b
b‘HryY‘
```

解码

```pythonimport base58a=b‘HryY‘b=base58.b58encode(a)bb‘233‘```
