thistuple = ("apple", "banana", "cherry") for i in range(len(thistuple)): print(thistuple[i]) Try it Yourself » Using a While LoopYou can loop through the tuple items by using a while loop.Use the len() function to determine the length of the tuple, then start at 0 and...
Loop through sequences: used for iterating over lists, strings, tuples, dictionaries, etc., and perform various operations on it, based on the conditions specified by the user. Example: Calculate the average of list of numbers numbers = [10, 20, 30, 40, 50] # definite iteration # run...
When we have a for loop inside another for loop, it’s called a nested for loop. There are multiple applications of a nested for loop. Consider the list example above. The for loop prints out individual words from the list. But what if we want to print out the individual characters of...
These elements are put into a tuple (x, y). We then iterate through the resulting list of tuples in the outermost for loop. The output of the third technique, therefore, is quite different: List comprehension: a1 b1 a1 b2 a2 b1 a2 b2 a3 b1 a3 b2...
In this example, color is the loop variable, while the colors list is the target collection. Each time through the loop, color takes on a successive item from colors. In this loop, the body consists of a call to print() that displays the value on the screen. This loop runs once for...
In Python, we use a for loop to iterate over various sequences, such as lists, tuples, sets, strings, or dictionaries. The for loop allows you to iterate through each element of a sequence and perform certain operations on it. In this tutorial, we will e

Python Tuple Length We use the len() function to find the number of items present in a tuple. For example, cars = ('BMW', 'Tesla', 'Ford', 'Toyota') print('Total Items:', len(cars)) # Output: Total Items: 4 Iterate Through a Tuple We use the for loop to iterate over the ...
Iterator is like range(11), compare to list = [0,1,...,10] all data is stored in memory. Iterator only generates values from looping through the object. # to get iterator from range function x = range(10) iter(x) x.__iter__() ...
If the sequences are not the same length, the result has the length of the shorter one(如果两个序列长度不一致,结果长度为短的序列长度). >>> zip('Anne','Elk') [('A','E'), ('n','l'), ('n','k')] You can use tuple assignment in afor loopto traverse a list of tuples: ...
