24 Jun 2017 Hi ! I regularly face the situation where I want to iterate over the values of a dictionary. var data = {} for key in data: data[key] With Python,
the key-value pair type, for initializing from a list of key-value pairs, or for looping entries in the same order
interface ObjectConstructor { /** * Copy the values of all of the enumerable own PropertyKey): T; set
Python provides one _keys () _method to get all keys from a python dictionary. Then we can iterate through the keys one by one and print out the value for each key. my_dict = {"one": 1,"two":2,"three":3,"four":4} for key in my_dict.keys(): print("Key : {} , Value : {}".format(key,my_dict[key])) This program will print the same output as the above two. In this case, you need to use dict () to generate the new_prices dictionary from the iterator returned by map (). Note that discount () returns a tuple of the form (key, value), where current_price [0] represents the key and round (current_price [1] * 0.95, 2) represents the new value. Then we use the “for loop” to iterate the keys and values of the dictionary. k,v are the variables.
