Lambda functions in Python are anonymous functions that can be defined in a single line of code. They are often used in situations where a function is required for a short period of time and defining a named function would be unnecessary.
It is not possible to use if-elif statements directly in a lambda function. However, you can use a ternary operator to achieve similar functionality. The syntax for a ternary operator is:
```python
value_if_true if condition else value_if_false
```
For example, if you want to define a lambda function that returns the square of a number if it is greater than 5 and the cube of the number otherwise, you can use the following code:
```python
lambda x: x**2 if x > 5 else x**3
```
This lambda function checks if the input value `x` is greater than 5. If it is, it returns the square of `x`. Otherwise, it returns the cube of `x`.
