Python

Python is an object-oriented, strictly, dynamically typed, lexically scoped programming language
Its object model is quite flexible (single-dispatch, metaclasses, everything is an object), and somewhat similar to that of Smalltalk. Python has some functional programming features: first-class functions, map(), reduce(), list comprehensions, and lexical closures. Python is a very "free-form" language with very few ways of invariant construction.

Comparing Python with Java

Python is expected to run slower than Java, but they also take much less time to develop. Python code is typically 3-5 times shorter than equivalent Java code. This difference can be attributed to Python's built-in high-level data types and its dynamic typing.


Java code 
public class HelloWorld
{
    public static void main (String[] args)
    {
        System.out.println("Hello, world!");
    }
}
 
if ( a > b )
{

    a = b;
    b = c;
}

Python code
print "Hello, world!"
 

 

 

 

 
if  a > b :
    a = b
    b = c
 

 

 

 

 

 

 

 

 

 Comparing Python with C++

Almost everything said for Java also applies for C++, just more so: where Python code is typically 3-5 times shorter than equivalent Java code, it is often 5-10 times shorter than equivalent C++ code! Anecdotal evidence suggests that one Python programmer can finish in two months what two C++ programmers can't complete in a year. Python shines as a glue language, used to combine components written in C++.

Delete SMS - Example

# import the built-in modules
import MDM
 
# Initialize
res = MDM.send('AT+CMGF=1\r', 0)
res = MDM.receive(5)
res = MDM.send('AT+CNMI=2,1\r', 0)
res = MDM.receive(5)
MDM.send('AT+CMGD=?\r', 0)
MemSMS = MDM.receive(20)
startSearch = 0
StartSearchIndex = MemSMS.find('(')+1
LastSearchIndex = MemSMS.find(')')
nextComma = MemSMS.find(',',StartSearchIndex,LastSearchIndex)
#search the next sms
if ( nextComma != -1):
    while ( nextComma < LastSearchIndex ):
        SMSIndex = MemSMS[StartSearchIndex : nextComma]
        print SMSIndex
        MDM.send('AT+CMGD=', 0)
        MDM.send(SMSIndex,0)
        MDM.send('\r',0)
        res = MDM.receive(20)
        print res
        StartSearchIndex = nextComma + 1
        nextComma = MemSMS.find(',',StartSearchIndex,LastSearchIndex)
#delete the last sms
SMSIndex = MemSMS[StartSearchIndex : LastSearchIndex]
if (SMSIndex != ''):
    MDM.send('AT+CMGD=', 0)
    MDM.send(SMSIndex,0)
    MDM.send('\r',0)
    res = MDM.receive(20)
