The combination of parse and length

General Usage
1

Hello,
Why is the following combination wrong?

w = "Hello"
print(parse(Int,length(w)))

Thank you.

length(w) is already an integer, you don’t need to parse it.

Hi,
Thanks.
So, when we try to convert one type to the same type, we get an error.

convert is different, convert(::Type{T}, x::T} -> x is generically defined, so you can convert(Int, 2). However, parse is something you specifically do to string-ly values, hence the error you saw.

Hi,
Thank you so much for your reply.
I didn’t mean the convert function.
