There are ways to iterate through key-value pairs. Here are some examples to help you understand better. Example 1: Access only the keys of the dictionary. dict1 = {"Brand": "BMW", "Color": "Black", "Date": 1964} for key in dict1: print(key) Run Output: BrandColorDate Example...
As you can see, the dictionary contains key-value pairs of stock symbols and their prices. We can iterate over it and print each stock's information on a different line as follows (using for loop). 1for key, value in portfolio.items() : 2 print("The stock " + key + " has a pri...
10.2 Python for Loop through by Key and Value Usedict.items()which returns a view object that gives a list of dictionary’s (key, value) tuple pairs. You can iterate over tuple to get the key and value. # Loop through by Key and Value technology={"Course":"python","Fee":4000,"Dur...
App.config for multiple groups of same key/value pairs App.config for release and another for debug app.config giving problem('Unrecognized configuration section ) app.config multiple values for a key App.config not being referenced app.config or settings.settings App.Config with |DataDirectory|\...
Next, we used the key to get access the value. Alternatively, we can use the items method in a dictionary, which returns an object containing a list of key and value pairs in tuple. We can assign them simultaneously to two variables (tuple assignment); see the example below. Sign in ...
The function returns an iterator resulting an index and row data as pairs. This method is useful when you need to consider the index while manipulating rows. Our initial DataFrame: data = {'CustomerID': [1, 2, 3], 'Name': ['John', 'Emily', 'Michael'], ...
In Python 2, there was aiteritems()method that returned an iterator over the dictionary’s key-value pairs. However, starting from Python 3, the items() method itself returns a view object that behaves likeiteritems() from Python 2. ...
Finally, since you'll often want both the keys and the values when iterating over a hash table, the hash table clauses support a using subclause at the end of the hash table clause. (loop for k being the hash-keys in h using (hash-value v) ...) (loop for v being the hash-va...

Here, we created a map and inserted 3 key-value pairs in the map. When we use the for...of loop to traverse the map elements in each iteration, we can get the key and value shown in the code below.Open Compiler const output = document.getElementById("output"); const map ...
