Vowel or Consonant Python

Following code will identify that entered character is a vowel or consonant.

Code::

def vowel(str):
    if(str=='a' or str=='e' or str=='i' or str=='o' or str=='u' or str=='A' or str=='E' or str=='I' or str=='O' or str=='U'):
        print("Vowel")
    else:
        print("Consonant")
while True:                                                #for only one character 
    
    a=input("Enter a Character: ")
    if(len(a)==1):
        break
    else:
        print("Try Again!!")
        continue
vowel(a)
    

Output:

Length of a String in Python

Following code is used to calculate length of a string using user defined length function :

Code::

def length(l):
    count=0
    for j in l:
        count=count+1
    return count
    
a=input("Enter String:")
c=length(a)
print("Length is :",c)

Output:

Greater of three Number in Python

Functions are defined in python using def keyword .Following will illustrate the concept.

Code::

def max(a,b,c):
    if(a>b and a>c):
        print ("Greater is :",a)
    elif(b>c and b>a):
        print("Greater is : ",b)
    else:
        print("Greater is :",c)
        
     
a=input("Enter First No:")
b=input("Enter Second no.:")
c=input("Enter Third no:")

max(a,b,c)

Output:

List and Tuple Datatype in Python

List and Tuple Both are datatypes in Python .These are similar to each other and used to store data of different types.But the only difference in list and tuple is that we can edit data in list but we can not edit data in tuple

For Example:

List =['76','23','25','85']

Tuple=('75','6','7')

Question:
	Write a program which accepts a sequence of comma-separated numbers from console and generate a list and a tuple which contains every number.
	Suppose the following input is supplied to the program:
	34,67,55,33,12,98
	Then, the output should be:
	['34', '67', '55', '33', '12', '98']
	('34', '67', '55', '33', '12', '98')

Code::

var=input("Enter Values Using Comma ',':")

n=var.split(",") # for constructing list from sequence

d=tuple(n)        # for constructing tuple

print ("List is :",n)

print ("Tuple is :",d)

Output:

Dictionary datatype Python

Question:
	With a given integral number n, write a program to generate a dictionary that contains (i, i*i) such that is an integral number between 1 and n (both included). and then the program should print the dictionary.
	Suppose the following input is supplied to the program:
	8
	Then, the output should be:
	{1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64}

Code::

dict={}              #dict is of type dictionary

i=input("Enter any Number:")

for j in (range(1,i+1)):

 dict[j]=j*j

print(dict)

Output:

Factorial of a Number Python

Following Code will Calculate the factorial of a number :

Code::

fact=1
i=input("Enter Any Number:")
for j in (range(1,i+1)):                #range function for iteration from 1 to i+1
 fact=fact*j

print(fact)



Note:   Take care of the space in the code which leads to formation of blocks

Output:

National Flag ("Tiranga") Using Java

Following Code will create Our National Flag("Tiranga") using Java  Applet 

Code::

import java.applet.*;
 import java.awt.*;
