Python For


There are two types of loops in Python, for and while.

The 'for' loop

Python For Dummies

For loops iterate over a given sequence. Here is an example:

For loops can iterate over a sequence of numbers using the 'range' and 'xrange' functions. The difference between range and xrange is that the range function returns a new list with numbers of that specified range, whereas xrange returns an iterator, which is more efficient. (Python 3 uses the range function, which acts like xrange). Note that the range function is zero based.

'while' loops

Python For Loop

'break' and 'continue' statements

break is used to exit a for loop or a while loop, whereas continue is used to skip the current block, and return to the 'for' or 'while' statement. A few examples:

Can we use 'else' clause for loops?

Unlike languages like C,CPP. we can use else for loops. When the loop condition of 'for' or 'while' statement fails then code part in 'else' is executed. If a break statement is executed inside the for loop then the 'else' part is skipped.Note that the 'else' part is executed even if there is a continue statement.

Python Print

Here are a few examples:


Python Format String

Loop through and print out all even numbers from the numbers list in the same order they are received. Don't print any numbers that come after 237 in the sequence.
