The main problem with updating a string in Python is that the string object is immutable. This means that once a string has been created, it cannot be changed. This can be a problem if you want to update the string to include new information.
s = "Hello, world!" s = s.replace("Hello", "Goodbye") print(s)
s = “Hello, world!”
s = s.replace(“Hello”, “Goodbye”)
Operations with string
In Python, you can use the string data type to store text. You can use the string data type to store text that you want to work with later. You can also use the string data type to store text that you want to display on a screen.
String updates examples
One common use of string updates is to change the text of a string in place. For example, you might want to change the name of a file. You can do this by using the replace() function:
file_name = “new_name.txt”
file_name = “old_name.txt”
replace(file_name, “new_name”, “old_name”)
