Python if Keyword

Print "YES" if x larger than 3:

Definition and Usage

The if keyword is used to create conditional statements (if statements), and allows you to execute a block of code only if a condition is True.

Use the else keyword to execute code if the condition is False, see example below.

Print "YES" if x is larger than 6, otherwise print "NO":

x = 5
if x > 6:
print("YES")
else:
print("NO")

The else keyword.
