Python Program to Replace Selected Character with * in a String

 Python Program to Replace Selected Character with * in a String


Hey There Python Geeks,

In this python tutorial, I have shown how to replace selected character with * in a string.

Consider a string : str = "hello youtube'

For character we ask the user to select a character : char = input("Enter a character that can be replaced")

Create a function called replace_char and pass the string(str) to it, you can name a function whatever you want  and that can be done as : def replace_char(str):

To check for every element we use for loop and can be written as : for i in str:

If the character and the element which is in the string matches exactly the same, we need to replace it with *, that can be done as : if char==i:
str.replace(char , " ")

And at last we need to return the string(str) : return str.replace(char , " ")

We successfully replaced the character with * which is present in the string, now what if a character is not present in the string?. For that we can use else statement to print character is not present in the string(str) that can be done as : else:
                    return "Selected character is not present in the string"

Now, the code can be written as :
                  str = "hello youtube"
                  char = input("Enter a character to be replaced")
                  def replace_char(str):
                        for i in str:
                              if char==i:
                                   return replace.(char , " ")
                        else:
                                return "Selected character is not present in the string"

                  print(replace_char(str))

Python Program to Swap First and Last Element of a Given List

Python Program to Swap First and Last Element of a Given List Hey Python Geeks , In this python tutorial ,  I have shown how to swap first and last element of a list. Consider a python list : list = [1,2,3,4,5,6,7,8,9] Create a python function called Swap that takes above python list as input, you can name it whatever you want and that can be written as : def Swap(list): Now, we have to swap first element to last element and that can be done as : list[0],list[-1]=list[-1], list[0] list[0] is the first element of the list list[-1] is the last element of the list We swapped them successfully, now call the function to see the swapped list and that can be done as : Swap(list) The code can be written as :             list = [1,2,3,4,5,6,7,8,9]             print("List before swapping",list)             def swap(list): ...

Python Program to Calculate the Average of Numbers in a Given List

  Hey There, In this blog, I have shown how to calculate average of numbers in a given list.Average can be calculated as :                           Average = (Sum of all the numbers)/(Total numbers) Here the given list is :  list = [1,2,3,4,5,6,7,8,9] Sum can be calculated as :  sum_all = sum(list) Total numbers can be calculated as :  length = len(list) Now, Average will be :   avg = (sum_all/length) Printing the Average as :    print("Average is : ",avg) The above code can be written in a single line as :                          print("Average of numbers is : ", sum(list)/len(list)) Output :  Python Program to Calculate the Average of Numbers in a Given List Video Tutorial:

Python Program to Put Even and Odd Elements of a List into Two Different Lists

Image
  Hey There, In this blog, I have shown how to put even an odd elements of a list into two different lists. Consider the given list as : list = [1,2,3,4,5,6,7,8,9] Take list for even elements : even_list = [ ] Take list for odd elements = odd_list = [ ] To check each element in the given list we will use for loop, that can be written as : for i in list: To know a element is even, we divide it by 2. If element remainder is zero then it is a even number. That can be written as : if i%2 == 0: If that element is divisible by 2, then we add that element to the even_list and can be written as : even_list.append( i ) If it is not divisible by 2, then we append it to odd_list : odd_list.append( i ) So, the program can be written as :       list = [1,2,3,4,5,6,7,8,9]       even_list = [ ]       odd_list = [ ]       for i in list:            if...
