👉 In mathematics and computer science, a partial function is a function that is defined on a subset of its domain but not all of it. In other words, it's like defining a function on a part of your set, but only on some parts.
For example, let's say we have the following function:
```python
def f(x):
return x
2 + 3
x - 5
# Let's define partial functions
partial_f = lambda y: (f(y),
