Xiaobian consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubt of "what should be paid attention to in python variable assignment". Next, please follow the editor to study!

1. Variables in variable assignment Python do not need to be declared, and the operation of variable assignment is the process of variable declaration and definition.

Each variable is created in memory and includes information about the identity, name, and data of the variable.

2. Each variable must be assigned before it is used, and the variable will not be created until the variable is assigned.

Example

#! / usr/bin/python#-*-coding: UTF-8-*-counter = 100# assign integer variable miles = 1000.0 # floating point name = "John" # what are the advantages of string print counterprint milesprint namePython? 1. Simple and easy to use. Compared with traditional languages such as CumberCure +, Java, C#, Python has less strict requirements on code format.

2. Python is open source, everyone can see the source code, and it can be ported to many platforms.

3. Python is object-oriented, which can support both process-oriented programming and object-oriented programming.

4. Python is an interpretive language. Programs written by Python do not need to be compiled into binary code and can be run directly from the source code.

5. Python has powerful functions, has many modules, and can basically achieve all the common functions.

At this point, the study of "what should be paid attention to in the assignment of python variables" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
