Make the code print out the following output using a for loop:

John Smith: +37682929928

Marry Simpons: +423998200919

So, the code should loop over the dictionary items and in each iteration should print out the dictionary key, a colon, a space, and the corresponding  value.

Note: If you plan to use string formatting here, please be aware that Udemy uses Python 3.5 and the f"{}" syntax only works with Python 3.6+. Consider using the "%s" syntax instead.
