The simplest way to append one string to another is by using the addition operator. The same as you use to add two numbers.
|
1 2 3 4 5 |
pre_text = "This is" post_text = " text." text = pre_text + post_text print(text) |
This code concatenates two strings and displays the result to the console.
This is text
Notice, that the post_text variable has a space before the text. It’s important for separating words.
If you have a list of words that you want to join, but there are no spaces between them, you can add words to a list and merge them with the join function.
|
1 2 3 4 5 6 |
pre_text = "This" mid_text = "is" post_text = "text." text = " ".join([pre_text, mid_text, post_text]) print(text) |
Space before join is a separator to separate the words. This is the result.
This is text.
Append Words using the For Loop
A string in Python is a list of characters. You can loop through each element of a string and add them to the end of another string.
|
1 2 3 4 5 6 7 8 |
pre_text = "This is" post_text = " text." for char in post_text: pre_text += char print(pre_text) print("Final result:", pre_text) |
With each step inside the loop, the variable is printed out to the console.
This is This is t This is te This is tex This is text This is text. Final result: This is text.
