The "if elif else" statement is a conditional statement in Python that allows a program to execute different blocks of code depending on whether a certain condition is true or false. The basic syntax of an if elif else statement is as follows:
```
if condition1:
# code to execute if condition1 is true
elif condition2:
# code to execute if condition2 is true
else:
# code to execute if neither condition1 nor condition2 is true
```
If condition1 is true, the code in the first block will be executed. If condition1 is false, the program moves on to the next condition, condition2. If condition2 is true, the code in the second block will be executed. If both condition1 and condition2 are false, the code in the else block will be executed.
The "elif" keyword stands for "else if" and allows the program to check for multiple conditions. It can be used multiple times within an if elif else statement to test for multiple conditions.
