Strings & Formatting
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 β 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 β single or double;
- Triple quotes are used for multiline text;
- f-strings allow dynamic values to be inserted into strings.
