May 4, 2017 · In Python 2.x the range function actually returned a list that the for loop would iterate through. In Python 3.x, the range function is it's own type, and is actually a generator function so the numbers are produced on the fly as the for loop is executing. You can still create a list from a range function if you pass it into a list like so.

[Update: for Python3 (the currently maintained versions of Python) the range() function always returns the dynamic, "lazy evaluation" iterator; the older versions of Python (2.x) which returned a statically allocated list of integers are now officially obsolete (after years of …

for i in range(4, 10, 2): print(i) in the above code, range has 3 parameters : Start of Range (inclusive) End of Range (Exclusive) Incremental value; For more clarity refer for the java representation of above python code: for (int i=4; i<10; i+=2){ System.out.println(i) }

Sep 2, 2011 · $ python -m timeit "reversed(range(10))" 1000000 loops, best of 3: 0.538 usec per loop bene's answer (the very first, but very sketchy at that time): $ python -m timeit "range(9,-1,-1)" 1000000 loops, best of 3: 0.401 usec per loop The last option is easy to remember using the range(n-1,-1,-1) notation by Val Neekman.

Passing only a single numeric value to either function will return the standard range output to the integer ceiling value of the input parameter (so if you gave it 5.5, it would return range(6).) Edit: the code below is now available as package on pypi: Franges

Mar 28, 2012 · You may notice that the range function works only in ascending order without the third parameter. If you use it without the third parameter in the range block, it will not work. for i in range(10,-11) The above loop will not work. For the above loop to work, you have to use the third parameter as a negative number. for i in range(10,-11,-1)

python 2.7. Is it possible to do this: print "Enter a number between 1 and 10:" number = raw_input("> ") if number in range(1, 5): print "You entered a number in the range of 1 to 5" elif number in range(6, 10): print "You entered a number in the range of 6 to 10" else: print "Your number wasn't in the correct range"

Aug 16, 2013 · Instead of doing an overly complicated function like most of the answers above I just did this. simple_range = [ x*0.1 for x in range(-100, 100) ] By changing the range count to 100 I now get my range of -10 through 10 by using the standard range function. So if you need it by 0.2 then just do range(-200, 200) and so on etc
