Simple Programs in Python

The following Python section contains a wide collection of basic Python programming examples.
including conditional statements,loop.

1. Write a Program to display the message "Good Morning!!"

	print("Good Morning!!")




	output:
	Good Morning!!

print() function is used to display string which is within quotation.

2. Assign two numbers in two variables n1 and n2.The task is to write a Python program to find the addition of these two numbers.
   

   # Python program to add two numbers
   n1 = 10
   n2 = 20
     
   # Adding two nos
   sum = n1 + n2
     
   # printing values
   print("Sum of {0} and {1} is {2}" .format(n1, n2, sum))	
   

   	Output:
   	Sum of 10 and 20 is 30
   

   In that case the value of n1 will be shown in {0}, the value of n2 will be shown in {1} and the value of sum will be shown in {2}
   The same number of spaces must be used in the same block of code,Otherwise Python will show error.
   

   if 9>5:
     print("9 is greter than 5")
     print("5 is less than 9")	
   

   The above code is correct.
   
   

   if 9>5:
     print("9 is greter than 5")
        print("5 is less than 9")		
   

   The above code is incorrect.Error will be displayed.

   Example of Python Syntax

   Python is a user friendly language because of its intelligent syntax structure.
   Let's do a simple Python program and you will get an idea of how programming in Python looks like.
   

   #Simple Python Program to see whether a user is Minor or Adult.
   # getting user's name 
   print("Enter your name:")
   name = input()
   # getting user's age
   print("Enter your age:")
   age = int(input())
   # condition to check whether user is Minor or Adult
   if( age >= 18 ):
       print( name, ' is Adult.')
   else:
       print( name, ' is Minor.')
   

   Output
   
   Enter your name:
   Rishi
   Enter your age:
   19
   Rishi is Adult.
   

   
   Carefully, look at all print() statements given above.Could you notice that first two print()statements are enclosed in double quotes and the next two print() statements are enclosed in single quotes.
   print("Enter your name:")
   print("Enter your age:")
   statements enclosed in double quotes
   
   print( name, ' is Adult.')
   print( name, ' is Minor.')
   statements enclosed in single quotes
   
   

3. Python Multiline Statements

In Python a new line means a new statement. But sometimes, you may want to split a statement in two or more lines.
It may be to aid readability. You can do so in the following ways.

i. Use a backward slash


>>> print("Hello students\
 how are you?")

	output
	Hello students how are you?

You can also use it to distribute a statement.

>>>x\
=\
5
>>> print(x)

Output:

5	

ii. Put the String in Triple Quotes


>>> print("""Hello students
       how are you?""")	

Output:

Hello students
     how are you?	

>>> ns='''he\
ll\
o'''
>>> print(ns)	

hello	

iii. Multiple Statements in One Line

>>>x=5;print(x);	

output:
5	




4. Python Variables

Data type is not necessary to declare a variable in Python Programming language.Python variables are created by assigning values of desired type.
Example
Variables in Python:


>>>x = 5
>>>print(x)
5
>>>x="Hello, World!"
>>>print(x)
Hello, World	




5. Python Comments

Comments are used for code documentation.
Python Comments start with a #
Example
Comments in Python:


#This is a comment.
print("Hello, students!!")
