We can iterate through dictionary keys one by one using afor loop. country_capitals = {"United States":"Washington D.C.","Italy":"Rome"}# print dictionary keys one by oneforcountryincountry_capitals:print(country)print()# print dictionary values one by oneforcountryincountry_capitals: ...
Python iterate through dictionary sorted 正如您在屏幕截图中看到的,输出显示了排序的键和值。 阅读: Python 字典副本带示例 按照顺序遍历字典 Python 在这一节中,我们将讨论如何以顺序方法迭代一个字典。 在这个例子中,我们将使用 list comprehension 方法,在这个函数中,我们已经设置了用于迭代字典值的键和值变量,...
We can iterate through a dictionary using a for-loop and access the individual keys and their corresponding values. Let us see this with an example. person = {"name": "Jessa", "country": "USA", "telephone": 1178} # Iterating the dictionary using for-loop print('key', ':', 'value...
1. Iterate a Dictionary in Python To iterate through a dictionary, we can use Python for loop. Let’s say, we want to print all elements in a dictionary, then we will use for loop as shown in the below example: Python 1 2 3 4 cubes = {1:1, 2:8, 3:21, 4:64, 5:125}...
A dictionary in Python contains key-value pairs. You can iterate through its keys using thekeys()method: myDict = {"A":2,"B":5,"C":6} foriinmyDict.keys(): print("Key"+" "+i) Output: Key A Key B Key C The above code is...
