input: Write a function to create a dictionary in Python with given key-value pairs. The function should take a list of tuples where each tuple contains a key and a value, and return a dictionary that maps each key to its corresponding value.
  
  assert create_dict([("FirstName", "John")]) == {"FirstName": "John"}
  assert create_dict([("FirstName", "John"), ("LastName", "Doe")]) == {"FirstName": "John", "LastName": "Doe"}
  assert create_dict([]) == {}
output: def create_dict(lst):
      return dict(lst)
