The iterable created in the example above is [0, 1, 2].Using a While LoopYou can loop through the list items by using a while loop.Use the len() function to determine the length of the list, then start at 0 and loop your way through the list items by referring to their indexes....
As we can see we are using a variablei, which represents every single element stored in the list, one by one. Our loop will run as many times, as there are elements in the lists. For example, inmyListthere are 6 elements, thus the above loop will run 6 times. 如我们所见,我们正在...
We can have nested lists inside another list. loop_nested.py #!/usr/bin/python nums = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] for i in nums: for e in i: print(e, end=' ') print() We have a two-dimensional list of integers. We loop over the elements with twoforloops...
In this article, we’ll explore the Python for loop in detail and learn to iterate over different sequences including lists, tuples, and more. Additionally, we’ll learn to control the flow of the loop using thebreak and continue statements. When to use for Loop Anytime you have need to...
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
append(column) # nextCells is a list of column lists. while True: # Main program loop. print('\n\n\n\n\n') # Separate each step with newlines. currentCells = copy.deepcopy(nextCells) # Print currentCells on the screen: for y in range(HEIGHT): for x in range(WIDTH): print(...
# this first kind of for-loop goes through a list for number in the_count: print "This is count %d" % number # same as above for fruit in fruits: print "A fruit of type: %s" % fruit # also we can go through mixed lists too ...

Lists#列表 Lists are another type of object in Python. They are used to store an indexed list of items.A list is created using square brackets with commas separating items.The certain item in the list can be accessed by using its index in square bracke
