Is there a greater than but less than function in python?

Question

I have this code I'm just playing with, As I'm new to python, which is this: ``` a = 0 while a < 10: a = a + 1 print("A is Less than 10") ``` I want to add some more code that says: If a is more than 10 but less than 20, print this: I tried: ``` a = 0 while a < 10: a = a + 1 print("A is Less than 10") while a < 20: a = a + 1 print("A is More than 10, but less than 20.") ``` But all that does is print "A is more than 10, but less than 20" Basically, is there a "Less than but greater than" function in python? I'm running version 3 by the way.

Accepted Answer

```
while 10 < a < 20:
    whatever
```

This doesn't work in most languages, but Python supports it. Note that you should probably be using a `for` loop:

```
for a in range(11, 20):
    whatever
```

or if you just want to test a single number rather than looping, use an `if`:

```
if 10 < a < 20:
    whatever
```

Be careful with the boundary conditions. When your first loop ends, `a` is set to `10`. (In fact, it's already set to 10 when you print the last "less than 10" message.) If you immediately check whether it's greater than 10, you'll find it's not.
