From a YAML file I get the string “2.0:0.25:10.0”.
How can I convert it to a StepRange?
```julia
tsr="2.0:0.25:10.0"
TSR=eval(tsr) # not working
```

I’d avoid eval and just parse the numbers from the string using `nums = parse.(Float64,split(tsr,":"))` and then construct the range using those, `range(nums[1],nums[3],step=nums[2])`

gives:

`range(nums[1],nums[3],step=nums[2])`
should work

Yea, you are quoting code from my post that I didn’t write!

```julia
TSR=replace(tsr,':'=>',')
eval(Meta.parse("(:)("*TSR*')'))
```
or better
```julia
eval(Meta.parse(tsr))
```
