Create an online video course, reach students across the globe, and earn money. Verify whether data is valid, i.e. This can be slow, … Almost everywhere. That’s what we’ll tackle next. What is the difference between range and xrange? xrange on the other hand, generates an object that creates the number(s) required in the range. Yes. Programming languages are a lot like actual languages.

This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages.. With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc. It isn’t necessary, but can be very useful when used right. Note: You can add individual elements to the list by using the extend() method as well. As the for loop is executed, Python goes through each element in this list. Hang out at websites like and to see how other programmers use the language and get access to sample code. Thus, for x in range(0, 100) basically creates a temporary list with numbers from 0 to 100. It works exactly like range, except that it is faster and more memory efficient. Run this program with "Sea Rose" as input: $ python
