This article shows you how to carry out the simple implementation of the Python Helloworld program, the content is concise and easy to understand, it will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

For a friend who has learned a programming language, he is sure to remember the word Helloworld deeply. Almost in the early days of learning the language, we all use this simple Mini Program to have an in-depth understanding of the programming language. So today I will introduce the implementation of Python Helloworld program for you.

Before starting the creation of the Python Helloworld program, you first need to create a new file c:\ test.py

Write something like this in this file.

Str = "hello world"

Print str

In this way, we have written a script.

Execute such a statement in the command line of python

Execfile ("c:\\ test.py")

So, you can see the result. Ha

Now we have one more requirement, that is, we need to use a separate file to write some configuration parameters.

For example, now we build such a file Global.py in the root directory of C disk.

Write some sentences in it: str1 = "hello world2"

So how do we use them: change the test.py to something like this.

Import sys sys.path.append (.') Import Global str = "hello world" print str print Global.str1

Now we can execute such a statement in python command line

Execfile ("c:\\ test.py") trouble shooting:

You may encounter such a situation during the implementation of a Python Helloworld program

Import Global ImportError: No module named Global

This is because he did not find the corresponding Global file under C:

Let's make sure first.

Check the current working directory

Import os os.getcwd ()

At this time, it is possible to display the installation directory of the python

Of course I can't find Global.py.

What we need to do is os.chdir ("c:\")

Then we execute os.getcwd (), and see if the working directory has changed.

Now let's do it again: execfile ("c:\\ test.py")

OK.

Of course, we can also do this:

C:\ > python test.py hello world hello world2 the above content is how to implement the Python Helloworld program simply. Have you learned the knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
