Python Numbers
Python Numbers
There are three numeric types in Python:
- int
- float
- complex
Variables of numeric types are created when you assign a value to them:
Example
x = 1
# int
y = 2.8 # float
z = 1j # complex
To verify the type of any object in Python, use the type()
function:
Int
Int, or integer, is a whole number, positive or negative, without decimals, of unlimited length.
Example
Integers:
x = 1
y = 35656222554887711
z =
-3255522
print(type(x))
print(type(y))
print(type(z))

Float
Float, or "floating point number" is a number, positive or negative, containing one or more decimals.
Float can also be scientific numbers with an "e" to indicate the power of 10.
Example
Floats:
x = 35e3
y = 12E4
z = -87.7e100
print(type(x))
print(type(y))
print(type(z))

Complex
Complex numbers are written with a "j" as the imaginary part:
