在for循环中使用多个表达式

Question

It is possible to use multiple expression in go loop like:

for _, err := range errs; err != nil  {

    }

Or I have to do like:

for _, err := range errs {
        if err != nil {
         statement
        }
    }

Answer 1

Per the documentation:

ForStmt = "for" [ Condition | ForClause | RangeClause ] Block .
Condition = Expression .

You can either have a Condition, or a ForClause, or a RangeClause. You cannot combine them.
