On running the above program, we get the following output:
Sometimes, you need to repeat a task multiple time or you may need to repeat the task either a
certain number of times or until a condition is satisfied. In Python, the statements that are used
to repeat a set of instructions are called iterative or looping statements. Looping statements are
very useful and necessary for developing applications.
Python provides two types of looping statements—for and while. The for statement is used
to repeat an instruction or a set of instructions a fixed number of times. Whereas, the while
statement is used to repeat a set of instructions until a condition evaluates to true. Let’s discuss
these constructs in brief.
THE FOR STATEMENT
for each item
The for statement executes a simple or compound statement for a in sequence
fixed number of times. The syntax of the for statement is given below:
Last item True
for <variable> in <iterator>:
reached?
