The tuple() function creates an ordered, immutable sequence of elements. It’s useful for storing multiple values, ensuring data consistency, and improving performance over lists.
Example
numbers = tuple([1, 2, 3, 4])
print(numbers)Output:
(1, 2, 3, 4)Converts a list into a tuple.
Syntax
tuple(iterable)- iterable (optional) → A sequence (
list,string,range) to convert into a tuple. - Returns → An immutable tuple.
1. Creating a Tuple
t = (10, 20, 30)
print(t)
# Output: (10, 20, 30)Tuples store multiple items in an ordered manner.
2. Creating a Tuple from a String
word = "hello"
t = tuple(word)
print(t)
# Output: ('h', 'e', 'l', 'l', 'o')Breaks a string into characters.
3. Single-Element Tuple (Must Include a Comma)
single = (5,)
print(single)
# Output: (5,)Using (5) creates an integer, but (5,) creates a tuple.
4. Unpacking a Tuple
person = ("Alice", 25, "Engineer")
name, age, job = person
print(name) # Output: Alice
print(age) # Output: 25
print(job) # Output: EngineerAssigns each element to a variable.
5. Tuple vs List (Key Differences)
| Feature | Tuple ( ) |
List [ ] |
|---|---|---|
| Mutable? | ❌ No (Immutable) | ✅ Yes (Mutable) |
| Performance | ✅ Faster | ❌ Slower |
By using tuple(), you can store immutable data efficiently, ensure data consistency, and improve performance. 🚀
