Even numbers in Python

Question

Does anyone know if Python has an in-built function to work to print out even values. Like range() for example.

Thanks

Answer 1

>>> if 100 % 2 == 0 : print "even"
...
even

Answer 2

Range has three parameters.

You can write range(0, 10, 2).

Answer 3

I don't know if this is what you want to hear, but it's pretty trivial to filter out odd values with list comprehension.

evens = [x for x in range(100) if x%2 == 0]

or

evens = [x for x in range(100) if x&1 == 0]

You could also use the optional step size parameter for range to count up by 2.

Answer 4

#This is not suggestible way to code in Python, but it gives a better understanding


numbers = range(1,10)

even = []

for i in numbers:

     if i%2 == 0:

       even.append(i)
print (even)

Answer 5

Just use a step of 2:

range(start, end, step)

Answer 6

Try:

range( 0, 10, 2 )
