Your first program: print()

print("ສະບາຍດີ ລາວ!")
print("ຂ້ອຍກຳລັງຮຽນ Python")

Write your first program in a single line!

Variables: boxes for your data

name = "ສົມພອນ"
age = 20
height = 1.68

print(name, age, height)

A variable is a labelled box that can hold anything.

if / else: let your program decide

age = 17

if age >= 18:
    print("ລົງທະບຽນໄດ້")
else:
    print("ຍັງນ້ອຍຢູ່")

How does a computer make decisions? With if.

Lists: many things in one place

cities = ["ວຽງຈັນ", "ຫຼວງພະບາງ", "ປາກເຊ"]
cities.append("ສະຫວັນນະເຂດ")

print(cities[0])
print(len(cities))

Can one variable hold many items? Yes, with a list.
