21 lip 2010 · When you iterate through dictionaries using the for .. in ..-syntax, it always iterates over the keys (the values are accessible using dictionary[key]). To iterate over key-value pairs, use the following: for k,v in dict.iteritems() in Python 2; for k,v in dict.items() in Python 3
Use the dictionary directly in a loop or comprehension if you want to iterate over the dictionary keys. To access the values, you can use the key lookup syntax, dict_object[key] . Use the .keys() method to iterate though the keys of a dictionary.
You can loop through a dictionary by using a for loop. When looping through a dictionary, the return value are the keys of the dictionary, but there are methods to return the values as well.
26 lip 2024 · To iterate through all values of a dictionary in Python using .values(), you can employ a for loop, accessing each value sequentially. This method allows you to process or display each individual value in the dictionary without explicitly referencing the corresponding keys.
Example 1: Access both key and value using items () for key, value in dt.items(): print(key, value) Output. Using a for loop, pass two loop variables key and value for iterable dt.items(). items() returns the key:value pairs. Print key and value.
Iterate Through a Dictionary. A dictionary is an ordered collection of items (starting from Python 3.7), therefore it maintains the order of its items. We can iterate through dictionary keys one by one using a for loop.
