If it reaches the last element in the sequence, it exits the loop. otherwise, it keeps on executing the statements present under the loop’s body Flow chart of a for loop Why use for loop? Let’s see the use for loop in Python. Definite Iteration: When we know how many times we ...
# 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 # notice we have to use %r since we don't know...
1.enumerate:返回2个值,1是当前的for循环的第几轮,2是循环得到的数值 enumerateworks by supplying a corresponding index to each element in the list that you pass it. Each time you go through the loop,indexwill be one greater, anditemwill be the next item in the sequence. choices = ['pizza...
Loop Through the Index NumbersYou can also loop through the list items by referring to their index number.Use the range() and len() functions to create a suitable iterable.Example Print all items by referring to their index number: thislist = ["apple", "banana", "cherry"]for i in ...

Use negative indexing for last elements Python supports negative indexing, which provides a safer way to access elements from the end of a list without knowing its exact length. The index -1 always refers to the last element, -2 to the second-to-last element, and so on. ...
The variable i iterates from the beginning to the end of the Python List, and when the program enters the body of the loop, the square of each element is calculated using the variable i and stored in a variable named ‘square’. Now that we understood how to write for loop in Python...
