Data Types
Data type specifies the type of value a variable requires to do various operations without causing an error. By default, python provides the following built-in data types:
Numeric data: int, float, complex
int: 3, -8, 0
float: 7.349, -9.0, 0.0000001
complex: 6 + 2i
more on numeric data types in the number chapter.
Text data: str
str: “Hello World!!!”, “Python Programming”
Example:
a=3.55
b=768
c="helnwl697"
print(type(a)) # float
print(type(b)) # int
print(type(c)) # stringNone:
None is used to define a null value. When we assign a None value to a variable, we are essentially resetting it to its original empty state which is not the same as zero, an empty string or a False value.
Boolean data:
Boolean data consists of values True or False.
a=True
b=False
c=None
print(a,b,c)
