Conceptual Review (page 22 of 55)

The simplest conditional is the if statement. The Boolean expression after the if statement is called the condition. Python supports the standard logical conditions.

1. Equals: x == y
2. Not Equals: x != y
3. Less than: x < y
4. Less than or equal to: x <= y
5. Greater than: x > y
6. Greater than or equal to: x >= y

Recall that we use a single "=" for assignment (i.e., x = 6) but the double "==" for comparison (i.e., x==6 would test if the value of x is equal to 6). Entering x=6 in a condition will result in a traceback because python cannot perform an assignment in a conditon. Instead, python can only evaluate whether a condition is True or False, which requires x==6.

Also, notice the not equal operator is != instead of <>, which is used in other programming languages.
