Python Programming Questions - Operation on STRING[SET-3]

1.Python Program to check if a string contains any special character

import re

def SpecialCharacterCheck(inputString):

    regex = re.compile(('[@_!#$%^&*()<>?/\|}{~:]'))

    if(regex.search(inputString) == None):

        print(inputString," Does Not HAve Any Special Character.")

    else:

        print(inputString," Does Has Special Character.")

inputString = input(" Enter The String : ")

SpecialCharacterCheck(inputString)

  Enter The String : Python$Regula&

  Python$Regula&  Does Has Special Character.

2.Python Program for Generating random strings until a given string is generated

import string

import random

import time

inputString = input(" Enter The String : ")

my_possibleCharacters = string.ascii_lowercase + string.digits + string.ascii_uppercase + ' ., !?;:'

my_attemptThis = ''.join(random.choice(my_possibleCharacters)

   for i in range(len(inputString)))

my_attemptNext = ''

com = False

iteration = 0

while com == False:

   print(my_attemptThis)

   my_attemptNext = ''

   com = True

   for i in range(len(inputString)):

      if my_attemptThis[i] != inputString[i]:

         com = False

         my_attemptNext = my_attemptNext + random.choice(my_possibleCharacters)

      else:

         my_attemptNext = my_attemptNext + inputString[i] 

   iteration = iteration + 1

   my_attemptThis = my_attemptNext

   time.sleep(0.1)

print("String matched after " + str(iteration) + " iterations")

 Enter The String : Python

3.Python Program to Find words which are greater than given length

inputString = input(" Enter The String : ")

word = inputString.split(' ')

requiredList = []

k  = int(input(" Enter The Minimum Length Required "))

for i in word:

    if len(i) > k:

        requiredList.append(i)

out = str(requiredList)

print(out)

  Enter The String : Computer Engineering Is Really fun With Python

  Enter The Minimum Length Required 5

  ['Computer', 'Engineering', 'Really', 'Python']

4. Python program for removing i-th character from a string

 inputString = input(" Enter The String : ")

 ithValue = int(input(" Enter The Index Value : "))

 newString = ''

 newString = newString + inputString.replace(inputString[ithValue],'',1)

 print(" String Before Removing : ",inputString)

 print(" String After Removing : ",newString)

  Enter The String : Computer

  Enter The Index Value : 7

  String Before Removing :  Computer

  String After Removing :  Compute

5.Python program to split and join a string

 inputString = input(" Enter The String : ")

word = inputString.split(' ')

#WithoutDelimeter

print(word)

#WithDelimiter

delimiter = input(" Enter The Delimiter You Want To Insert : ")

out = delimiter.join(word)

print(out)

  Enter The String : Python Is Easiest Programming Language.

  ['Python', 'Is', 'Easiest', 'Programming', 'Language.']

  Enter The Delimiter You Want To Insert : $$

  Python$$Is$$Easiest$$Programming$$Language.

  Enter The String : Python Is Easiest Programming Language.

  ['Python', 'Is', 'Easiest', 'Programming', 'Language.']

  Enter The Delimiter You Want To Insert :   $

  Python  $  Is  $  Easiest  $  Programming  $  Language.
