In Python, a data type is a classification that specifies which type of value a variable can hold. It defines the operations that can be performed on the data and the way the data is stored in memory. Python is a dynamically-typed language, which means that the data type of a variable is interpreted at runtime based on the type of value it holds.
Here are some common data types in Python:
Numeric Types:
Sequence Types:
Boolean Type:
Set Types:
Mapping Type:
None Type:
Other Types:
Python is designed to be flexible with types, and variables can change their types dynamically during execution. For example, a variable initially assigned an integer value can later be assigned a string or any other type of value.
x = 5 # x is of type int
x = "hello" # x is now of type str
Understanding and using appropriate data types is crucial for writing efficient and bug-free Python code.
