Addition and Product of a List Python

Question::

Define a function sum() and a function multiply() that sums and multiplies (respectively) all the numbers in a list of numbers. For example, sum([1, 2, 3, 4]) should return 10, and multiply([1, 2, 3, 4]) should return 24.

Code::

def add(l):

    s=0

    for j in l:

        s=s+int(j)

    return s

def multiply(l):

    m=1

    for j in l:

        m=m*int(j)

    return m

d=input("Enter List: ")

n=d.split(",")

print("Entered List=",n)

print("Addition is:",add(n))

print("Product is:",multiply(n))

Output::

"Rövarspråket" (Swedish for "robber's language")

Question:: Write a function translate() that will translate a text into "rövarspråket" (Swedish for "robber's language"). That is, double every consonant and place an occurrence of "o" in between. For example, translate("this is fun") should return the string "tothohisos isos fofunon".


Code::
def translate(str):
    consonants='bcdfghjklmnpqrstvwxyz'
    print("".join(l+'o'+l if l in consonants else l for l in str))

string=input("Enter Any String: ")

translate(string)

Output::

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:
