MWE:

```
using JuMP, GLPK
model = Model(GLPK.Optimizer)
@variable(model, x[i=1:4]>= 0.5, Int)
@objective(model, Min, sum(x))
optimize!(model)
for x in all_variables(model)
println("$(name(x)) = $(value(x))")
end
```

As you know, run it in `Jupyter notebook`

, you can get the output like this:

```
x[1] = 1.0
x[2] = 1.0
x[3] = 1.0
x[4] = 1.0
```

and when you just input `x[1]`

, you will get： x_1

So, I want to show my output like:

x_1 = 1.0\\
x_2 = 1.0\\
x_3 = 1.0\\
x_4 = 1.0

How to get these result with a simple code? And it will be the best if this result can be showed in REPL.

Thanks in advance!
