Variables and types

Store values and check their type with type().

8 minutes3 games

Python needs no let and no type: write a name, = and a value. The basic types:

int: whole number, 19.
float: decimal, 1.65.
str: text, "Huda".
bool: True or False (capitalised).
None: “no value”.

name"Huda"str

age19int

height1.65float

is_studentTruebool

Python

name = "Huda"
age = 19
height = 1.65
is_student = True
phone = None

print(name, age)
print(type(age), type(height), type(name), type(is_student), type(phone))

x, y = 3, 7    # two at once
x, y = y, x    # swap
print(x, y)

Step by step1 / 4

▶score = 10
2score = score + 5
3score += 1
4print(score)

Variables

score

Output

…

Complete the code

Complete: create city with the value Alex and print it.

city  "Alex"
(city)

What's the output?

a, b = 1, 2
a, b = b, a
print(a, b)
