Python supports many data types. The string data type is popular in python for operations related to texts. In python, they are enclosed by the double quotes. In this article, we will understand how to copy python strings.

There are four different ways to copy a string in Python which are:

• Copy string by appending character by character
• Copy string using for loop and indexing
• Copy string using while loop
• Copy string using equal operator “=”
• Copy string using string slicing technique

Copy the Strings by Appending Characters in Each Step

The most basic implementation we can do is to copy the characters of the string one by one and perform the desired operation like appending into other strings etc.

The approach of the method can be as follows:

First, make the string. Next, iterate through the string, take the characters in each step, and append them into another string.

Example (1)

first_text=input("Enter the text you want to be copied:")
second_text=""
print(f"The second text is: {second_text}")
for x in first_text:
    second_text=second_text+x
print(f"The text you entered is: {first_text}")
print(f"The second text now is: {second_text}")

Output:

The second text is:

The text you entered is: hello this is the text

The second text now is: hello, this is the text

Explanation:

1. First, we took the first text as the input using the input function of python, and we stored the text in the variable named first_text.
2. Next, we created an empty string named second_string. We printed the second string using the print statement and used the string formatting technique here.
3. Next, we iterated through the first text and appended each character of the string into the second string using the concatenation operation.
4. We printed the first string and the second string afterward.

Copy String using for loop and Indexing

In the previous code, we understood how to get the characters of the string using the for a loop. We can slightly tweak the above program to get the characters through indexing. Next, we can concatenate the character into the empty string.

Example (2)

first_text=input("Enter the text you want to be copied:")
second_text=""
print(f"The second text is: {second_text}")
n=len(first_text)
for i  in range(n):
    second_text=second_text+first_text[i]
print(f"The text you entered is: {first_text}")
print(f"The second text now is: {second_text}")

Output:

The second text is:

The text you entered is: hello, this is a text

The second text now is: hello, this is a text

Explanation:

The basic logic of the above program is similar to our previous code. The only difference is that instead of accessing the characters one by one, we are indexing the characters of the strings and concatenating the characters into the empty string.

Similarly, we can use the while loop to copy the string into another string.

Copy String using the While loop

Example (3)

first_text=input("Enter the text you want to be copied:")
second_text=""
print(f"The second text is: {second_text}")
n=len(first_text)
i=0
while(i<n):
    second_text=second_text+first_text[i]
    i=i+1
print(f"The text you entered is: {first_text}")
print(f"The second text now is: {second_text}")

Output:

The second text is:

The text you entered is: This is a text

The second text now is: This is a text

Copy the Whole String using the “=” Operator

The “=” operator is used to assign values to the variables. We can copy any string as a whole into another string with the help of this operator.

Example (4)

first_text=input("Enter the text you want to be copied:")
second_text=""
print(f"The second text is: {second_text}")
second_text=first_text
print(f"The text you entered is: {first_text}")
print(f"The second text now is: {second_text}")

Output:

The second text is:

The text you entered is: This is a text

The second text now is: This is a text

Copy String in Python using String Slicing

We can use string slicing to copy the strings into another string. Slicing is a technique of accessing part of a string using indexing.

Example (5)

first_text=input("Enter the text you want to be copied:")
second_text=""
print(f"The second text is: {second_text}")
second_text=first_text[:]
print(f"The text you entered is: {first_text}")
print(f"The second text now is: {second_text}")

Output:

The second text is:

The text you entered is: This is a string

The second text now is: This is a string

Conclusion

In this string, we learned how to copy sting using different techniques in python. We used indexing and standard iteration methods to copy the characters and the whole string.
