I know how to use both for loops and if statements on separate lines, such as:
>>> a = [2,3,4,5,6,7,8,9,0]
... xyz = [0,12,4,6,242,7,9]
... for x in xyz:
... if x in a:
... print(x)
0,4,6,7,9
And I know I can use a list comprehension to combine these when the statements are simple, such as:
print([x for x in xyz if x in a])
But what I can't find is a good example anywhere (to copy and learn from) demonstrating a complex set of commands (not just "print x") that occur following a combination of a for loop and some if statements. Something that I would expect looks like:
for x in xyz if x not in a:
print(x...)
Is this just not the way python is supposed to work?
You can use generator expressions like this:
gen = (x for x in xyz if x not in a)
for x in gen:
print x
