Now let’s talk about loops in Python. First we’ll look at two slightly more familiar looping methods and then we’ll look at the idiomatic way to loop in Python. while If we wanted to mimic the behavior of our traditional C-styleforloop in Python, we could use awhileloop: colors=[...
While Loop In Python A while statement iterates a block of code till the controlling expression evaluates to True. While loop favors indefinite iteration, which means we don't specify how many times the loop will run in advance. In Python, a basic while loop looks like this: ...
However, if you just want to operate on the value of the sequence without considering its corresponding position in the sequence, you can use the for loop given below. python fruits = ["Apple","Mango","Banana","Pineapple","Strawberry"]foriinfruits:if(i=="Mango"):print("Mango found in...

To show how Python can use each of these different class types in the same way, we can first create aforloopthat iterates through atupleof objects. Then we can call the methods without being concerned about which class type each object is. We will only assume that these methods actually ...
In itertools, you’ll find a function called chain() that allows you to iterate over multiple Python dictionaries one at a time. In the following sections, you’ll learn how to use these two tools for iterating over multiple dictionaries in a single loop. You’ll also learn how both tool...
