# Tutorial: using the len built in function
# ------------------------------------------------------------------------------------

# len is used to find the amount of items in an object (ie an array)
array = ["1", "2", "3"]
# the len can be printed
print("The length of the array is: ", len(array))

# len can also be used to find the amount of characters in a string.
text = "text"
# the len can also be stored in a variable
textlen = len(text)
print("The amount of characters in the variable text is: ", textlen)

# ------------------------------------------------------------------------------------
# Challenge: 1. create an array with your own data and get the length of it.
#            2. create a program that checks the length of the string "Hello World!".
