Python - Datatype

Every thing in python has a datatype. There are various types of datatypes in python. Broadly they are divided into numbers and strings. Let's have a look at both.

Python Numbers

Integers, float and complex numbers fall under python’s number category. They are represented in python in following ways:

Int

Integers can be of any length, it is only limited by the memory available.

Float

A floating point number is accurate up to 15 decimal places. Integer and floating points are separated by decimal points.

Complex

Complex numbers are written in the form, x + yj, where x is the real part and y is the imaginary part.

Python Strings

String is sequence of unicode characters. We can use single quotes or double quotes to represent strings. Multiline strings can be denoted using triple quotes''' or """.

Conversion of data type

We can convert between different data types by using different type conversion functions like int(), float(), str() etc.
