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...
forxinrange(2,30,3): print(x) Try it Yourself » Else in For Loop Theelsekeyword in aforloop specifies a block of code to be executed when the loop is finished: Example Print all numbers from 0 to 5, and print a message when the loop has ended: ...
x = (i for i in range(10)) Iterator 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__() Map retu...

The basic format of a for loop is: for temporary variable in Pending data:. The loop is a traversal loop, which can be understood as extracting elements from the data to be processed one by one, and making each element execute an internal statement block once. For example, the element ...
