I would like to split a list taking characters after the split point into another list

I think the answer is along the lines of 

```
[re.sub(r'......', '', i) for i in x] 

```

Here is the list I want to split

```
['260=2.31', '264=0.68', '265=0.25', '266=3.56', '267=0.05', '268=6.71']

```

putting all before the "=" into one list

```
['260','264','265','266','267','268']

```

and all after the "=" into another list

```
['2.31','0.68','0.25','3.56','0.05','6.71']

```

thanks!
