Let’s also see how to iterate over both indexes and values of a given 2-D array using Pythonforloop along with thenp.ndenumerate()function. For example, # Iterate 2-D array and get indexes & values for index, value in np.ndenumerate(arr): ...
With Python 3.7, a dictionary is guaranteed to be iterated in the insertion order of keys. If you need to iterate over a dictionary in sorted order of its keys or values, you can pass the dictionary’s entries to thesorted()function, which returns a list of tuples. You can get the ...
public static void PrintDict<K, V>(Dictionary<K, V> dict) { foreach (K key in dict.Keys) { Console.WriteLine(key + " : " + dict[key]); } } public static void Main() { Dictionary<string, string> dict = new Dictionary<string, string> { { "key1", "value1" }, { "key2"...
