for loop interger

it seems that the for loop need to have integer arguments

is there another one where we can have a sep value like 0.1 which is not integer value

like for j in range ( 10.2 , 50, 5.5)

or what else should i use instead?


Here’s a really quick hack for float_range I just coded for fun:

def float_range(min, max, step=1.0):
    ret = []
    amount_of_values = (max-min) / step
    step_amount = (max-min) / amount_of_values
    for i in range(amount_of_values):
        ret.append(min + step_amount * i)
    return ret

for i in float_range(10.2, 50, 5.5):
    print i

You can find another, perhaps more comprehensive implementation at .

What about this…

j = 1
j_end = 10
j_step = 0.5
while j < j_end:
 j = j + j_step
 print j

Another way (must have at least Python 2.3 or 2.4 (can’t recall when yield became a standard keyword)):

def frange(min, max, step = 1.0):
     while min < max:
          min += step
          yield min

It doesn’t check for error values or anything, but that should be easy to add…

integers are nice but sometimes you deal with real numbers!

but is are the min and max again limited to integer

let say that i have a loop that is function of angles

let say from minang = 100.5 degrees to a max of 210.8 degrees

and i want to step with an increment of 1.1 degree
is the for loop able to deal with that of if i have to make an independant set of variables inside to deal with it ?

or may be the while loop is easier to deal with this kind of situtation


I don’t think it matters as long as you don’t clobber your variables inside the loop.
