Python Copy String

Today, our discussion topic is how to copy python strings. We have discussed different easy and helpful ways to copy a python string. As we already know, the string is absolute. If we assign the string variable value to another string variable directly, it will not replicate it to the newly created variable. Both string variables point toward the same string. Since the string is absolute, we can access a new replica of the string by placing an empty string to the already created string. Let’s explore every method by placing a null string to the original string with the help of Spyder Compiler.

Example 1:

To copy the string in Python, we use the method to take characters one by one from the user to insert in a string, then simply copy the whole string to the newly created string just like we did in the below program code. So, let’s move to implementing our first program code via Spyder Compiler.

Create a new file from the Spyder compiler file menu and start writing your first program code. In our first statement, we use a print statement that gets a string from the user. Then we create and initialize a blank string. We can then create another string variable which stores copied strings. For loop states that ‘x’ is already present in “strOne”. So, the first character is initialized to ‘x’. The loop executes, and the characters are stored one by one in the variable ‘x’ and get initialized to ‘strTwo’.

In short, the user enters the first string then it will copy to the new string, and the print statement displays both the original and the copied string.

print("Enter your first String: ")

strOne = input()

strTwo = ""

for x in strOne:

strTwo = strTwo + x

print("\nYour first String =", strOne)

print("\nNCopied String =", strOne)

Now save and dry run the code to check how this manual method works.

Example 2:

In our second program, we use a For Loop with range() method where it takes a character one by one from the user and then puts it into the string, then simply copies the whole string to the newly created string just like we did earlier. So let’s move to implementing our second program code and make changes in the program file.

In our first statement, we use a print statement that gets a string from the user. Then we create and initialize a blank string. We can then create another string variable which stores copied strings. The range() method states that values are placed sequentially. By default, it initiates from ‘0’ and then increases the value by 1 until the number is less than the value passed as its parameter. So, the program executes the first character of the string and is initialized to ‘strTwo’.

Similarly, in our next execution, the value increments, and another character is stored in the variable ‘x’ and gets initialized to ‘strTwo’. In short, using this method we can easily copy strings from one to another.

print("Enter your first String: ")

strOne = input()

strTwo = ""

for x in range(len(strOne))

strTwo = strTwo + strOne[x]

print("\nYour first String =", strOne)

print("\nNCopied String =", strOne)

Again, dry run the program code and check how the range() method works.

Example 3:

In our third program, we use the slice() method. We use this function to slice the string and then can get a new copied string. Slicing can be performed using start and end index points. If we don’t put any starting and ending index points, then you will get either a whole string or a copy of the older one. In our first statement, we use a print statement that gets a string from the user. Then we create and initialize a blank string. We can then create another string variable and assign the original string. At last, the print statement prints the copied string on the console screen.

print("Your first String: ", end="")

str_one = input()

str_two = str_one[:]

print("\nCopied String =", str_two)

Again, dry run the program code and check how this method works.

Conclusion:

I hope that the aforementioned methods are really helpful to you, and you can now understand how easily you can copy the string in python. All illustrations can be implemented and used on any operating system.
