# InfoDB is a data structure with expected Keys and Values

# Append to List a Dictionary of key/values related to a person and cars

  1. Index with For loop:
x = len(InfoDb)
print(x)
i = 0
def print_data(d_rec):
    print(d_rec["FirstName"], d_rec["LastName"])  # using comma puts space between values
    print("\t", "Residence:", d_rec["Residence"]) # \t is a tab indent
    print("\t", "Birth Day:", d_rec["DOB"])
    print("\t", "Cars: ", end="")  # end="" make sure no return occurs
    print(", ".join(d_rec["Owns_Cars"]))  # join allows printing a string list with separator
    print()
for i in range (x):
    record = InfoDb[i]
    print_data(record)
    i += 1
