Simple example for using asterisks for unpacking variables (this example is the one without asterisks)

unpacking-kwargs-example3.py

# single parameter function
# expect kwargs as dict
def func3(kwargs):
  print(kwargs)
  
# you can call the function like this
func3({'var1':'hello', 'var2':'world', 'var3':'!'})  

# but you can't do something like this
func3(var1='hello', var2='world', var3='!')
