What Is a String?
A string (str
) is a sequence of characters enclosed in quotes.
It can hold names, messages, sentences, symbols, or even be empty.
In Python, you can use:
- Single quotes:
'hello'
- Double quotes:
"hello"
Both forms work the same way.
Multiline strings
Sometimes, you need to write text that spans several lines — like a paragraph or a message. For this, Python uses triple quotes:
'''...'''
;"""..."""
.
These preserve line breaks and spacing.
String Formatting
Sometimes you need to insert values into a string, such as names, numbers, or results. Python supports several formatting methods, but the most common and readable is the f-string.
f-Strings
With an f-string, you place variables or expressions inside {}
directly in the text.
Add the letter f
before the opening quote to enable this feature.
Summary
- Strings in Python are written using quotes — single or double;
- Triple quotes are used for multiline text;
- f-strings allow dynamic values to be inserted into strings.
Task
-
Write a short greeting using a name stored in a variable.
-
Try to format it using an f-string.
For example: if the name is
"Alex"
, the program should display a personalized message.

Can you show me an example of how to use an f-string with a variable?
What happens if I forget the 'f' before the string?
Can I use f-strings with numbers or only with text?
Awesome!
