For loop with multiple variables python
Python's for loop is an iterator-based loop (that's why bruno desthuilliers says that it "works for all iterables (lists, tuples, sets, dicts, iterators, generators etc)". A string is also another common type of iterable). Show
Let's say you have a list of tuples. Using that nomenclature you shared, one can iterate through both the keys and values simultaneously. For instance:
will give you the output:
If you use a dictionary, you'll also gonna be able to do this. The difference here is the need for .items()
The difference between dictionary and dictionary.items() is the following
Using dictionary.items() we'll get a view object containig the key-value pairs of the dictionary, as tuples in a list. In other words, with dictionary.items() you'll also get a list of tuples. If you don't use it, you'll get
If you want to get the same output using a simple list, you'll have to use something like enumerate()
If you don't, you'll get
So, this naturally raises the question... do I need always a list of tuples? No. Using enumerate() we'll get an enumerate object.

In simple terms, A dictionary maps one value to another, similar to how an English dictionary is used to map one word to its definition. Here, we will use the The following code uses the
Output:
In the code above, we also use the Use the enumerate() Function for Multiple Assignments in a List in PythonThe The following code uses the
Output:
Here, we take two lists, namely Use the zip() Function for Multiple Assignments in a Tuple or a List in PythonThe The

Here, the Related Article - Python LoopCan you use multiple variables in a for loop Python?The use of multiple variables in a for loop in Python can be applied to lists or dictionaries, but it does not work for a general error. These multiple assignments of variables simultaneously, in the same line of code, are known as iterable unpacking.
Can a for loop have multiple loop variables?Yes, I can declare multiple variables in a for-loop. And you, too, can now declare multiple variables, in a for-loop, as follows: Just separate the multiple variables in the initialization statement with commas. Do not forget to end the complete initialization statement with a semicolon.
How do you use a loop with multiple variables?For Loop with two variables in Java. public class forloop {. public static void main(String[] args) {. // for loop with two variable i & j.. // i will start with 0 and keep on incrementing till 10.. // j will start with 10 and keep on decrementing till 0.. for (int i = 0, j = 10; i < 10 && j > 0; i++, j--) {.
