How to combine two for loops

Lets say i'm trying to print 0 to 25 and 75 to 100. Right now I have:

for x in range(0, 26):
    print(x)
for x in range(75, 101):
    print(x)

Is there any way to combine these into a single for loop that lead to:

print(x)

?

Something along the lines of:

for x in range(0, 26) and range(75, 101):
    print(x)

Using List Comprehension:

[i for j in (range(0, 26), range(75, 101)) for i in j]

Here's a way to do it with list comprehension and a single line, if you don't want to import anything. You basically add all the numbers to a list, then print the list as a long string with newline characters after each number.

print("\n".join([str(x) for x in range(0,101) if x < 26 or x > 74]))

for x in list(range(0, 26)) + list(range(75, 101)):
    print(x)

You can concatenate two lists by adding them.

You need the itertools.chain():

Make an iterator that returns elements from the first iterable until it is exhausted, then proceeds to the next iterable, until all of the iterables are exhausted. 

from itertools import chain

for x in chain(range(0, 26), range(75, 101)):
    print(x)

Works for both Python 2 and 3.
