+# Tuples
+
+Tuples is a data type to group a fixed number of items of potentially different types into a single compound structure. Unlike arrays, tuples have a set length and can contain elements of varying types. Once a tuple is created, its size cannot change.
+For example:
+
+```rust
+{{#include ../../../listings/ch00-getting-started/cairo_cheatsheet/src/tuple_example.cairo}}
+```
