%s - String (or any object with a string representation, like numbers) Here are some basic argument specifiers you should know: The string which returns from the "repr" method of that object is formatted as the string. Print("%s is %d years old." % (name, age))Īny object which is not a string can be formatted using the %s operator as well. To use two or more argument specifiers, use a tuple (parentheses): # This prints out "John is 23 years old." Let's say you have a variable called "name" with your user name in it, and you would then like to print(out a greeting to that user.) # This prints out "Hello, John!" The "%" operator is used to format a set of variables enclosed in a "tuple" (a fixed size list), together with a format string, which contains normal text together with "argument specifiers", special symbols like "%s" and "%d". Print out the final string variable.Python uses C-style string formatting to create new, formatted strings.The final string is stored in the modified_str variable. We are not using the third argument as we are replacing all characters in the string. You can see that this method is taking only two arguments here: the first one is the character we want to replace, and the second one is the symbol to use by replacing the characters. Replace all occurrences of the character in the string using the replace method.Also, get the symbol that we want to use by replacing the character read in the above step.Get the character that we want to replace in the string.the user input string is stored in the input_string variable. We are converting the value returned by input() to String by wrapping it with str(). Take the input string from the user by using the ‘input()’ method.
String modifiers python code#
(The source code is available here) : Description : replace (c ,symbol ) #4 print ( "Modified String is : " ,modified_str ) #5 Symbol = input ( "Enter the symbol you want to replace with : " ) #3 Input_string = str ( input ( "Enter a string : " ) ) #1Ĭ = input ( "Enter a character you want to modify in the above string : " ) #2 Python String comes with an inbuilt method called replace() for replacing all occurrences of a substring in a string with a different substring. We can use the process described above, but in this blog post, I will show you one different way to solve this problem. If any replaceable character is found, replace it with the symbol and join it.
During the iteration process, keep building the new string by joining the characters. So, we need to create one different string using the characters of the provided string. We can’t change a character in a string directly. We can use one for-loop and compare each character of the string one by one. Using a loop, we can iterate over a string.
if the character is found 5 times in the string, it will replace all 5 occurrences. It will replace all occurrences of the character,i.e. Our program will replace the character with the symbol in the given string. First, we will take all the inputs from the user: String, character to replace, and the symbol.

In this tutorial, we will learn how to replace all occurrences of a character with a different symbol in a string. Python program to replace all occurrences of a character with a symbol in a string :
