''' Purpose: print integers from a user-specified upward interval n ... m
'''

# get interval of interest
reply = input( "Enter start and end: " ) #'2 7'
m, n = reply.split() # ['2','7']

m, n = int( m ), int ( n ) # 2, 7

# print out integers m to n


for i in range( m, n + 1 , 2) :
    print( i )

# If you forget the range, Python says "oh that's just a pair
# of two numbers!" and that's probably not what we want.
# ranges go from i to j-1 but pairs aren't a range so it's the
# actual numbers. (3,5) is still 3 and 5 but range(3,5) is 3,4

# range(i,j) -> values i to j-1         # Write this down!
# If we want to include the last value, what do we need to do? Add 1
# to the ending value!
# Mathematically it's like [m, n)
# It includes the starting value but goes all the way up to
# but not including the ending value
