Counting parameters
Define a function param_count that takes a variable number of parameters. The function should return the number of arguments it was called with.
For example, param_count() should return 0, while param_count(2, 3, 4) should return 3.

==== SOLUTION ====
You can achieve this by using the special variable `*args`, which collects all positional arguments into a tuple within the function. Then, you can return the length of this tuple. Here’s how you can do it:
“`python
def param_count(*args):
      return len(args)
# Test cases
print(param_count()) # Output: 0
print(param_count(2, 3, 4)) # Output: 3
“`
Explanation:
1. `def param_count(*args):`: This line defines a function named `param_count` that accepts a variable number of positional arguments using `*args`.
2. `return len(args)`: This line returns the length of the `args` tuple, which represents the number of arguments passed to the function.
This implementation correctly counts the number of parameters passed to the function, regardless of how many there are.
