The Python language has a lot of similarities to Perl, C and Java. Though, there are some specific differences between the languages.
First Python Program:
relative Mode Programming:
Calling up the interpreter exclusive of passing a script file as a parameter brings up the following on time:
$ python
Python 2.5 (r25:51908, Nov 6 2007, 16:54:01)
[GCC 4.1.2 20070925 (Red Hat 4.1.2-27)] on linux2
Type "help", "copyright", "credits" or "license" for more info.
>>>
The following text you have to type to the right of the Python prompt and push the Enter key:
>>> print "Hello, Python!";
This will generate following result:
Hello, Python!
Script Mode Programming:
Calling up the interpreter by a script parameter starts execution of the script and continues until the script is ended. When the script is ended, the interpreter is no longer active.
Let us write a easy Python program in a script. All python files will have conservatory .So place the following source code in a test.py file.
#!/usr/bin/python
print "Hello, Python!";
Here we implicit that you have Python interpreter available in /usr/bin directory. Now attempt to run this program as follows:
$ chmod +x test.py # This is to make file executable
$ python test.py
This will generate following outcome:
Hello, Python!
