The form for (;;) for an infinite loop is traditional, appearing in the standard reference The C Programming Language, and is often punningly pronounced "forever". The following example shows the use of for loop to iterate over a list of numbers. Iterator and iterable are two objects which work behind the mechanism of ‘for’ loop. If you forget to increment or decrement the counter, you will end up with an infinite loop. The following example illustrates the use of the for statement in python. ; Examples and usage in Python.

Note: It is suggested not to use this type of loops as it is a never ending infinite loop where the condition is always true and you have to forcefully terminate the compiler.
