#Basic Python Tutorial - Lesson One
#How data types work

num_1 = input("Give me a number: ")
num_2 = input("Give me another number: ")

print("At the moment, I am treating them as strings.")
print(num_1,"+",num_2, "=" ,num_1 + num_2)

print("But if I treat them as integers we get this.")
print(num_1, "+", num_2, "=", int(num_1) + int(num_2))
#When we treat the numbers as integers it will combine their total value
#Whereas when we treat the numbers as 'Strings' the script will place them side by side
#in the order they have been inputed.

#e.g. 
#     num_1 = input("Give me a number: ")   - For the purpose of this tutorial we have inputed the varible 2
#     num_2 = input("Give me another number: ") - Same again here
#
#
#     print(num_1,"+",num_2, "=" ,num_1 + num_2) - When we treat them as strings the output will be , 22
#
#     print(num_1, "+", num_2, "=", int(num_1) + int(num_2)) - But when we treat them as integers we get, 4
#
#
# When it is treating the variables as strings, adding them together just prints them out one after another 
# (we call this  “concatenating” strings). When I use the format “int(num_1)”, it tells the computer to convert the string 
# into an integer and then do the maths. If you give the computer numbers with decimals, you’ll see an error when it tries to add them.
