Hi,
I would like to delete several rows from a dataframe in one command. For example:
```julia
deleteat!(df, [row1, row2, row3])
```
Where row(n) is a variable and is given by the user. I can delete one row with readline():
```julia
if choice == "3"
print("\033c")
println("Which row to delete?")
dr = readline()
deleteat!(df, parse(Int64,dr))
CSV.write("FILE.csv", df)
println("Data deleted...")
println(df)
println("\n")
end
```
I tried nearly everything to delete multiple rows at once in one command, but without succes.
Is this possible in Julia?

I think, from what you posted, that your trouble is that you need to parse multiple input rows as an array, which you can do by broadcasting `parse` (with a dot):
```julia
julia> rows = readline()
1 2 3
"1 2 3"
julia> rows
"1 2 3"
julia> parse.(Int, split(rows))
3-element Vector{Int64}:
1
2
3
julia> df = DataFrame(A = 1:5, B = 6:10)
5×2 DataFrame
Row │ A B
│ Int64 Int64
─────┼──────────────
1 │ 1 6
2 │ 2 7
3 │ 3 8
4 │ 4 9
5 │ 5 10
julia> deleteat!(df, parse.(Int, split(rows)))
2×2 DataFrame
Row │ A B
│ Int64 Int64
─────┼──────────────
1 │ 4 9
2 │ 5 10
```

Thank you lmiq, that did the trick! I didn’t realize i had to put a “dot” after “parse”. I searched for half a day but didn’t realize that this was solution for my case. I will dive a bit more into the dot operator know ;-).
