“Golang -Karte” Code-Antworten

Initialisieren Sie die Karte in Golang

// By default maps in Go behaves like a default dictionary in python
m := make(map[string]int)

m["Dio"] = 3
m["Jonathan"] = 1
Joseph Joestar

Gehen Sie aus der Karte entfernen

m := map[string]string{"key1": "val1", "key2": "val2"}
delete(m, "key1")

Gehen Sie zur Karte hinzufügen

m := make(map[string]int)
m["numberOne"] = 1
m["numberTwo"] = 2
