elif Statement
Sometimes, the programmer may want to evaluate more than one condition, this can be done using an elif statement.
An elif statement works on the following principle,
- execute the block of code inside if statement if the initial expression evaluates to True. After execution return to the code out of the if block.
- execute the block of code inside the first elif statement if the expression inside it evaluates True. After execution return to the code out of the if block.
- execute the block of code inside the second elif statement if the expression inside it evaluates True. After execution return to the code out of the if block.

. - execute the block of code inside the nth elif statement if the expression inside it evaluates True. After execution return to the code out of the if block.
- execute the block of code inside else statement if none of the expression evaluates to True. After execution return to the code out of the if block.
Example:
num = 0
if (num < 0):
print("Number is negative.")
elif (num == 0):
print("Number is Zero.")
else:
print("Number is positive.")Output:
Number is Zero.
