Python looping over a dictionary In the following example, we loop over a Python dictionary. for_loop_dictionary.py #!/usr/bin/python data = { "de": "Germany", "sk": "Slovakia", "hu": "Hungary", "ru": "Russia" } for k, v in data.items(): print(f"{k} is an abbreviation ...

Iterate Dictionary using for loop What is for loop in Python In Python, the for loop is used to iterate over a sequence such as a list, string, tuple, other iterable objects such as range. With the help of for loop, we can iterate over each item present in the sequence and executes...
The reason why this loop works is because Python considers a “string” as a sequence of characters instead of looking at the string as a whole. Using the for loop to iterate over a Python list or tuple ListsandTuplesare iterable objects. Let’s look at how we can loop over the elemen...
This type of loop is used to iterate over a sequence (such as a list, tuple, dictionary, set, or string) or other iterable objects. It also supports iteration over a range of numbers. Here's an example: python for i in range(5): print("The number is:", i) This code will prin...
Python provides two different types of looping statements. Here, while loop is similar to the other programming language like C/C++ and Java. Whereas, the for loop is used for two purpose. First one is to iterate over the sequence likeList,Tuple,SetandDictionary. And the other one is to ...
The for loop in python is used to iterate over a given sequence. The sequence can be a string, a list, a tuple,a set, a dictionary, etc. As long as the length of the sequence is not reached, it will iterate over that sequence. The for loop contains initialization, the test expressi...
What is a Pythonforloop? Aforloop is used to repeat a block of code (encased in theforloop)nnumber of times. Theforloop is used to repeat the same action over a list of things. It’s one of a number of Python iterators. The basic syntax of theforloop looks like this: ...
One Line for Loop in Python The simplified “for loop” in Python is one line for loop, which iterates every value of an array or list. The one line for the loop is iterated over the “range()” function or other objects like an array, set, tuple, or dictionary. ...
