Nested Loops

Loops inside loops

You can put loops inside other loops:

for i := 0; i < 3; i++ {
    for j := 0; j < 3; j++ {
        fmt.Printf("(%d,%d) ", i, j)
    }
    fmt.Println()
}

The inner loop runs completely for each iteration of the outer loop. This prints a $3$ x $3$ grid of coordinate pairs. Nested loops are common for working with $2$ D data.
