Python range() Function
· The Python range type generates a sequence of integers by defining a start and the end point of the range. It is generally used with the for loop to iterate over a sequence of numbers.range() works differently in Python 2 and 3. In Python 2, there are two functions that
Python range() function
Example 3 – Python range() with specific start and end In this example, we will create a range object which represents a sequence that starts at 4 and ends before 8. As the default value of step is 1, we should get sequence of integers 4, 5, 6, 7.

By default, the start is included and the end is excluded, just like python’s built-in range() function. If you use keyword arguments and don’t specify either the start or the end of the range, then the Range’s bounds will be negative or positive infinity, respectively.

ForLoop
The ”range” function is seen so often in for statements that you might think range is part of the for syntax. It is not: it is a Python built-in function which returns a sequence following a specific pattern (most often sequential integers), which thus meets the requirement of providing a sequence for the for statement to iterate over.
Python for loop
#!/usr/bin/python word = “cloud” for let in word: print(let) We have a string defined. With the for loop, we print the letters of the word one by one to the terminal. $ ./for_loop_string.py c l o u d This is the output of the example. Python for loop else The for loop has an optional else statement which is executed when the looping has finished.

Allow `range(start, None, step)` for an endless range
Currently, to iterate over finite arithmetic sequences of integers, range is used, as in: for i in range(10): print(i) For an infinite arithmetic sequence, there are a few approaches. One can replace the ‘10’ with a long sequence of nines, write a generator function or just switch to a while loop, but the current ‘best’ way is using itertools: import itertools for i in itertools.count
