Basic to Advance Python Program

Armstrong number:

x = int(input("Please enter any number")) temp = x rev=0 while(x!=0): digit=x%10 rev=rev+digit**3 x=x//10 if(temp==rev): print("The given input in Armstrong Number ") else: print("The given input in not Armstrong Number ")

palindromic number:

x = int(input("Please enter any number")) temp = x rev=0 while(x!=0): digit=x%10 rev=rev*10+digit x=x//10 if(temp==rev): print("The given input in palindromic ") else: print("The given input in not palindromic ")

Simple menu:

print("1: \t learn python") print("2: \t learn java") print("3: \t go swimming") print("4: \t have dinner") print("5: \t Go to bed") print("0: \t Exit")

Menu in while loop:

while True: choice = input() if choice == "0": break; elif choice in "12345": print("You choose {}".format(choice)) else: print("please choose from here") print("1: \t learn python", "2: \t learn java", "3: \t go swimming", "4: \t have dinner", "5: \t Go to bed", "0: \t Exit")

code for greeting:

greeting = 'hello' print(greeting+ ' ' + input() )

Code for splitString:

splitstring = "You are the only one \n who can done any thing" print(splitstring)

tabbed string:

tabbedstring = "1\t 2\t 3" print(tabbedstring)

Another Split String:

anothersplitstring = """You can do any thing that you want from your soul""" print(anothersplitstring)

Split from any where:

str = 'yourname' str[4:8]

Largest no between two value:

a=input("please enter a no: ") b=input("please enter 2nd no: ") if(a>b ): print(a,"is largest no ") elif(b>a): print(b," is largest no") else: print("chai lelo")

Tuples and lists:

List ­­ A list is a dynamic array/sequence. It is ordered and indexable. A list is mutable. List constructors: [], list(). range() and xrange(): range(n) creates a list of n integers. Optional arguments are the starting integer and a stride. ● xrange is like range, except that it creates an iterator that produces the items in the list of integers instead of the list itself. Tuples ­­ A tuple is a sequence. A tuple is immutable. Tuple constructors: (), but really a comma; also tuple(). Tuples are like lists, but are not mutable. Python lists are (1) heterogeneous (2) indexable, and (3) dynamic. For example, we can add to a list and make it longer eg - a = [11, 22, 33] print(a)

Append():

a = [] a.append('aaa') a.append('bbb') a.append('ccc') a.append('ddd') print a

Use the string join operation to create a string that contains a colon as a separator:

content = [] content.append('finch') content.append('sparrow') content.append('thrush') content.append('jay') contentstr = ':'.join(content) print contentstr

Get keyword:

#To get the key words import keyword print(keyword.kwlist)

Convert Oct to dec:

# oct to dec a=int(input("Enter the number :"),8) #if we take 8 ,it will take value in octal form print("The number in dec is: ",a)

Convert Oct to bin:

#oct to bin a=int(input("Enter the number :"),8) #if we take 8 ,it will take value in octal form print("The number in dec is: ",bin(a))

Convert Oct to oct:

#take value in oct and print it in oct form a=int(input("Enter the number :"),8) #if we take 8 ,it will take value in octal form print("The number in dec is: ",oct(a))

Convert int to bin:

#int to bin a=int(input("Enter the number :")) #take value in integer and diplay it in binary form print("The number in dec is: ",bin(a))

Reverse number:

a=2 b=3 print("No. before reversing: ",a,b) a,b=b,a print("No after reversing is :",a,b)
