How do you duplicate a string in python?
I'm just starting some string manipulations and found this question. I was probably trying to do something like the OP, "usual me". The previous answers did not clear up my confusion, but after thinking a little about it I finally "got it". Show

The printed output is: In this tutorial, we are going to learn about multiple ways to copy a string in Python. Copying the stringConsider, we have the following string: To make a copy of a string, we can use the built-in slice syntax Example:
Similarly, we can also
do it by assigning a
or we can use the
This tutorial will introduce different methods to copy a string in Python. Before we move on to the different methods to copy a string in Python, we should keep in mind that a string cannot be directly copied. In Python, strings are immutable, meaning that their value cannot change over the course of the program. Being immutable also means that a string cannot directly have a copy. If a new variable is declared and is directly assigned the value of a given string variable, this would not create a copy of the original string. Instead, both of the created variables would point to the same string. However, there are a few loopholes that can be utilized to copy a string in Python. We will discuss all such methods below in this article. Use an Empty String to Get a Copy String in PythonWe start with the simplest method, which is very easy to implement. We need to add an empty string to the original string using the The following code uses an empty string to get a copy string in Python.
The above code provides the following output:
Use Slicing to Copy a String in PythonThe slice or the If both these values are not passed, the original string would be copied intact to the new variable. The following code uses slicing to copy a string in Python.
The above code provides the following output:
Use the str() Function to Copy a String in PythonThe The
following code uses the
The above code provides the following output:
Use String Formatting to Copy a String in PythonString formatting supplies a wide variety of customizations for the user to select from in the python code. The Although there is more than one way to implement string formatting in Python, the interpolation operator or The The following code uses string formatting to copy a string in Python.
The above code provides the following output:
Although copying a string can be achieved indirectly in Python, it is not essentially a recommended practice. The Moreover, these strings cannot really be mutated in any way; therefore, creating a copy is pretty much a waste of time and system memory.

How do you make a copy of a string?Copying one string to another - strcpy
strcpy can be used to copy one string to another. Remember that C strings are character arrays. You must pass character array, or pointer to character array to this function where string will be copied. The destination character array is the first parameter to strcpy .
How do you make duplicates in Python?In Python, we use = operator to create a copy of an object. You may think that this creates a new object; it doesn't. It only creates a new variable that shares the reference of the original object. Let's take an example where we create a list named old_list and pass an object reference to new_list using = operator.
What does Copy () do in Python?The Python copy() method creates a copy of an existing list. The copy() method is added to the end of a list object and so it does not accept any parameters. copy() returns a new list.
