Module 2

Game TimeRobots were not able to make decisions for themselves

Had to give them very precise instructions

Variables

a = 20b = 5c = a - b

Variables

a = 20b = 5c = a – b

print(a) a = 100 print(a)

Variables import random

a = 20b = 5c = a – b

print(a) a = random.randint(1, 10) print(a)

Strings

a“hello”

b“world”

c“helloworld”

a = “hello”b = “world”c = a + b

Strings

a“hello”

b“world”

c“hello world”

a = “hello”b = “world”c = a + “ ” + b

Strings can be concatenated

name = “Avilay” profession = “programmer” print(name + “ is a ” + profession)

Datatypes cannot be mixed age = 30 print(name + “is” + age + “years old”)

Ka-Boom!!

Datatypes cannot be mixedage = 30print(name + “is” + str(age) + “years old”)

Convert the number to a string using the str function

Datatypes cannot be mixedage = “30”print(name + “ is ” + age + “ years old ”)

Or just declare the variable age as a string.

Datatypes cannot be mixed your_age = input(“Your age?”) my_age = 30 older_by = my_age – your_age

Ka-Boom!!

Datatypes cannot be mixed your_age = int(input(“Your age?”)) my_age = 30 older_by = my_age – your_age

input function always returns a string. Convert it to a number using the int (for integer) function.
