You can loop through the list items by using a for loop:ExampleGet your own Python Server Print all items in the list, one by one: thislist = ["apple", "banana", "cherry"] for x in thislist: print(x) Try it Yourself » ...
Aloopis a sequence of instructions that is continually repeated until a certain condition is reached. For instance, we have a collection of items and we create a loop to go through all elements of the collection. In Python, we can loop over list elements with for and while statements, and...

Listsand other data sequence types can also be leveraged as iteration parameters inforloops. Rather than iterating through arange(), you can define a list and iterate through that list. We’ll assign a list to a variable, and then iterate through the list: sharks=['hammerhead','great white...
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...
Python for loop with string The following example uses Pythonforstatement to go through a string. for_loop_string.py #!/usr/bin/python word = "cloud" for let in word: print(let) We have a string defined. With theforloop, we print the letters of the word one by one to the terminal...
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

continues until the control has traversed through the end of therange() function, which is 5 in this case, and then the control returns back to the outermost loop, initializes the variable number to the next integer, prints the statement inside the print() function visits the inner loop ...
The first “one line for loop” is applied on the range from “(1,6)”, and the print statement is used to print out all the elements in the specified range. In the second part, a variable named “list_1” is initialized, and the “One line for loop” iterates through the element...
