python - How to make integer patterns? -

i want build sequence pattern, example have numbers 1, 2, 3.
1 first pattern, 2 second, , 3 third.

# assign patterns. first = 1 second = 2 third = 3   # make loop x in xrange(1, 100):     print(second)

this print second, want print number after every 2 integers.

so example:

1  2 - pattern 2 3  4 - pattern 2 5 6 - pattern 2 7 ...

how achieve sequence? can make integer patterns in loop, such integer 2 , after every 2 integers prints pattern2 integer returned.

xrange has step parameter. see documentation.

for x in xrange(1, 100, 2):     print(second)

to print pattern 1, 2 , 3 successively:

patterns = [first, second, third] x in xrange(1, 100):     print(patterns[x % 3])

to print third:

for x in xrange(1, 100):     if x % 3 == 0:         print(third)
