Variables in Python do not need to be declared. Each variable must be assigned a value before use. The variable will not be created until the variable is assigned a value.
In Python, a variable is a variable, it has no type. What we call "type" is the type of the object in memory pointed by the variable.
The equal sign (=) is used to assign values to variables.
The left side of the equal sign (=) operator is a variable name, and the right side of the equal sign (=) operator is the value stored in the variable.
Python3 has 6 most commonly used data types, which are:
Numbers (numbers)
String(String)
List(List)
Tuple(Tuple)
Sets (set)
Dictionaries (dictionary)
Among the six standard data types of Python3:
Immutable Data (3): Number, String, Tuple;
Variable data (3): List, Dictionary, Set ).
The above is the detailed content of What are the numeric types in Python?. For more information, please follow other related articles on the PHP Chinese website!

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Key features of Python include: 1. The syntax is concise and easy to understand, suitable for beginners; 2. Dynamic type system, improving development speed; 3. Rich standard library, supporting multiple tasks; 4. Strong community and ecosystem, providing extensive support; 5. Interpretation, suitable for scripting and rapid prototyping; 6. Multi-paradigm support, suitable for various programming styles.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
