String Concept in Python:-

The string is a collection of char, it will arrange multiple char using sequence. The string char index will be to start from 0 to length-1.

The string will be declared using  ' '" "  and  """


a= 'welcome'   #single line string
a= "welcome" #single line
a= """ welcome in scs """   #multiple line with proper syntax format

    


WAP to count total vowel and consonant in String?

s= 'welcome'    #['w','e','l','c','o','m','e']
c=0
d=0
for i in range(0,len(s)):
    if s[i]=='a' or s[i]=='e' or s[i]=='i' or s[i]=='o' or s[i]=='u':
        c=c+1
    else:
        d=d+1

print("vowel",c,"consonant",d)     


another way to create this program:-

s = input("Enter word")
v=0
c=0
for i in range(0,len(s)):
    if s[i] in ('a','e','i','o','u'):
        v=v+1
    else:
        c=c+1

print("Total vowel is ",v, "Consonent is ",c)        
    
another way to create this program:-

s = input("Enter word")
v=0
c=0
for ch in s:
    if ch in ('a','e','i','o','u'):
        v=v+1
    else:
        c=c+1

print("Total vowel is ",v, "Consonent is ",c)  

'

......................................................................
MOST OF THE STRING PROGRAM WILL BE RELATED WITH ASCII CODE HENCE PYTHON PROVIDE TWO DIFFERENT METHOD TO PERFORM OPERATION FROM
ASCII TO CHAR AND CHAR TO ASCII

1)  ord():-   this function is used to return the ascii code of particuar char
                   print(ord('a'))  #97   #char to ascii'

2)  chr():-  this function is used to return jhar from ascii code 

                    print(chr(65))   #A    #ascii to char


WAP to find max char in String?

s= 'ramesh'
m = s[0]
for i in range(1,len(s)):
   if m<s[i]:   #s<h
       m=s[i]
print(m) 


ASSIGNMENT:-

1)WAP to reverse string where vowel will be in the same position?

for example  Ramesh          hasemr

Solution:-

s="ramesh"
s1="";
c = 5
for i in range(0,len(s)):
    if s[i]=='a' or s[i]=='e' or s[i]=='i' or s[i]=='o' or s[i]=='u':
        s1+=s[i]
    else:
        if s[c-i]=='a' or s[c-i]=='e' or s[c-i]=='i' or s[c-i]=='o' or s[c-i]=='u':
            s1+=s[i]
        else:
            s1=s1+s[c-i]
         

print(s1)   

2) WAP to check palindrome in String?

example  madam, naman

Solution
s="madam"

c = len(s)-1
flag=True
for i in range(0,len(s)//2):
    if s[i]!=s[c-i]:
        flag=False
        break
 
if flag:
    print("pallindrom")
else:
    print("np")
     


3) WAP to convert a string from upper case to lower case and lower case to upper case?

Solution:-
s="MADAM"
s1=""

for i in range(0,len(s)):
   s1+=chr(ord(s[i])+32)
print(s1)

4) WAP to replace the string char from the next consecutive String char  (if char will be z then replace by a)?


   Manish  o.p  nbojti 


5) WAP to extract numeric, alphabets, and special char in separate string in any String?

s = "abcd123@7$f"

abcdf
123
@$


6)  WAP to display a number of repeated char in String?

hello     h 1 e 1 l 2 o 1

Solution of this program:-

s = "mangalam"

for i in range(0,len(s)):
    c=0
    
    for k in range(0,i):
        if s[i]==s[k]:
            break
    else:    
     for j in range(i,len(s)):
        if s[i]==s[j]:
            c=c+1
     else:
        print(s[i],c)

7)  WAP to validate emaild?  (@, ., the position of @ should be lesser of last dot position)

8)  WAP to display a strength of password that password is weak, medium, and Strong according to predefined cases?

Strong (at least 3 special char, non-consecutive, not belonging with first name and Lastname, one upper case char and numeric is mandatory, length minimum 6)

Medium (at least 2 special char, non-consecutive, length minimum 6)

  4. #predefine method of string
    1)capatlize()-Converts the first character to upper case
    implement-
    s1 = "hello, and hi"

    x = s1.capitalize()

    print (x)
    2)casefold()-Converts string into lower case
    implement-
    s2 = " Welcome To My World"

    x = s2.casefold()

    print(x)
    3)centre()-Returns a centered string
    implement-
    s3 = "banana"

    x = s3.center(20)

    print(x)
    4)count()-Returns the number of times a specified value occurs in a string
    implement-
    s4 = "I love mango,mango is yellow color "

    x = s4.count("mango")

    print(x)
    5)Upper()-Converts a string into upper case
    implement-
    s5 = "Hello my friends"

    x = s5.upper()

    print(x)
    6) translate()- method returns a string where some specified characters are replaced with the character described in a dictionary
    mydict = {65: 70};
    s6 = "Hello hi!";
    print(s6.translate(mydict));

    7)strip()-The strip() method removes any leading (spaces at the beginning) and trailing (spaces at the end) characters (space is the default leading character to remove)

    implement-
    s7 = " company "

    x = s7.strip()

    print("mnc", x, "TCS")
    8)isnumeric()- isnumeric() method returns True if all the characters are numeric (0-9), otherwise False.
    implement-
    s8 = "12345"

    x = s8.isnumeric()

    print(x)
    9) format()- method formats the specified value(s) and insert them inside the string's placeholder.
    example-
    Insert the price inside the placeholder, the price should be in fixed point, two-decimal format:

    implement-

    s9 = "For only {price:.2f} dollars!"
    print(s9.format(price = 49))
    10) islower()- method returns True if all the characters are in lower case, otherwise False.

    Numbers, symbols and spaces are not checked, only alphabet characters.
    Check if all the characters in the text are in lower case:

    s10 = "hello world!"

    x = s10.islower()

    print(x)
