In Python, there are scenarios where you need to join two or more strings into a single string or a single line. This operation is quite common in data manipulation, file handling, and basic string operations. This tutorial will guide you through how to join two lines in Python, along with various methods that can be used to perform this operation.
Prerequisites
For this tutorial, you should have a basic understanding of Python programming, and how to work with strings in Python.
Method 1: Using The “+” Operator
In Python, the “+” operator can be used to concatenate or join, two or more strings together.
|
1 2 3 4 |
line1 = "Hello" line2 = "World!" joined_line = line1 + " " + line2 print(joined_line) |
Method 2: Using The join() Method
The join() method is a string method in Python, used to join the elements of a list with the string it’s called on.
|
1 2 3 4 5 |
line1 = "Hello" line2 = "World!" lines = [line1, line2] joined_line = " ".join(lines) print(joined_line) |
Output:
Hello World!
Method 3: Using The format() Method
The format() function in Python is used to format a specified value(s) and insert them inside the string’s placeholder.
|
1 2 3 4 |
line1 = "Hello" line2 = "World!" joined_line = "{} {}".format(line1, line2) print(joined_line) |
Output:
Hello World!

# Using "+" Operator line1 = "Hello" line2 = "World!" joined_line = line1 + " " + line2 print(joined_line) # Using join() Method lines = [line1, line2] joined_line = " ".join(lines) print(joined_line) # Using format() method joined_line = "{} {}".format(line1, line2) print(joined_line) |
Conclusion
Python provides several ways to join lines including the “+” operator, the join() method, and the format() function. They all work in different ways but aim to achieve the same result, making Python a versatile and flexible programming language for data manipulation.
Remember, the choice of method depends on your specific use case and preferences.
