Practical application operations for Python Installation

If you have some problems with Python installation during the actual application process of Python installation, you can browse our article, our article is an introduction to its related content. I hope you will gain some benefits after reading our article.

Download the windows version. After the download is complete, double-click it and install it step by step.

 
 

  
  
*Python 2.5.2 Windows installer 
 
 

After installation, start Python command line and enter:

 
 

  
  
*Python 2.5.2 Windows installer  
 
 

If the output

 
 

  
  
"Hello World" 
 
 

It indicates that the installation is successful. Simple configuration: Right-click my computer-properties-advanced-environment variables and enter your python installation location in path, which is much simpler than java. My E: \ python25133 should be the parent level directory of pythonw.exe. Test: Create a folder. For example, create a text file under d \ code \ python and change it to hello. py. Enter

 
 

  
  
print "Hello World" 
 
 

Enter python hello in the installation path d \ code \ python at the command prompt. py, enter hello. py must set the environment variable.) The program will output Hello World. Let's look at another slightly complicated program.

 
 

  
  
integer1=raw_input("enter the first integer:\n")  
  
  
intinteger1=int(integer1)  
  
  
integer2=raw_input("enter the second integer:\n")  
  
  
intinteger2=int(integer2)  
  
  
sum=integer1+integer2  
  
  
print "The sum is ",sum 
 
 

Save as sum. py. The execution result is:

 
 

  
  
E:\>python e:\python\sum.py  
  
  
enter the first integer:  
  
  
8  
  
  
enter the second integer:  
  
  
11  
  
  
The sum is 19
