I have been trying to save multiple plots with different names through a loop.  
I am looking for the Julia equivalent of python script: plt.savefig('ID+str(i).‘png’).  
I tested this savefig(“C:/Julia\_data/ID”+str(i) “.pdf”) but obviously it does work.

In Julia you concatenate strings with `*`, not `+`.

It would be helpful for you to post the error message so we can confirm this is your problem.

I would also recommend using `joinpath` to create a path. It’s more robust if you want your code to run on multiple operating systems and I find it to be a good habit.

```julia
path = raw“C:\Julia_data”
savefig(joinpath(path,"ID" * str(i) * “.pdf”))

```
