Searching value in a List

Question::

Write a function is_member() that takes a value (i.e. a number, string, etc) x and a list of values a, and returns True if x is a member of a, False otherwise.

Code::
def is_member(d,n):
    for i in n:
        if(d==i):
            return True
    return False 
n=input("Enter list:")
nt=n.split(",")    
d=input("Enter Value to be searched:")
if(is_member(d,nt)):
    print("Yes it is Present")
else:

    print("No it is not Present")

Output::

String Palindrome or Not Python

Question::

Define a function reverse() that computes the reversal of a string. For example, reverse("I am testing") should return the string "gnitset ma I".

Code::
def reverse(l):
    return"".join(l[i] for i in range(len(l)-1,-1,-1)) 
name=input("Enter String:")
rev=reverse(name)
print("Reverse is:",rev)
if(rev==name):
    print("String is Palindrome")
else:

    print("Not a Palindrome")

Output::

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:
