if / else: let your program decide

How does a computer make decisions? With if.

if ກວດເງື່ອນໄຂ: ຖ້າແມ່ນຄວາມຈິງ (True) ຈະເຮັດໂຄດທີ່ຢູ່ຂ້າງລຸ່ມ, ຖ້າບໍ່ແມ່ນ ຈະໄປເຮັດ else.

ຈື່ໄວ້ 2 ຢ່າງ: ມີເຄື່ອງໝາຍ : ທ້າຍແຖວ ແລະ ໂຄດຂ້າງໃນຕ້ອງຫຍໍ້ໜ້າ 4 ຍະຫວ່າງ.

ຮຽນຕໍ່

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.

for loops: repeat without retyping

for i in range(1, 6):
    print("ຮອບທີ", i)

Count from 1 to 5 with a single line of logic.

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.
