Python Built-in Methods – Python tuple() Function

Python tuple() Function

Creates a tuple from an iterable


The tuple() function creates a tuple from an iterable.

The iterable may be a sequence (such as a string, list or range) or a collection (such as a dictionary, set or frozen set)



Parameter Condition Description
iterable Required A sequence or a collection


tuple() with no arguments creates an empty tuple.

T = tuple()
# Prints ()

You can convert any sequence (such as a string, list or range) into a tuple using a tuple() method.

# string into tuple
T = tuple('abc')
# Prints ('a', 'b', 'c')

# list into tuple
T = tuple([1, 2, 3])
# Prints (1, 2, 3)

# sequence into tuple
T = tuple(range(0, 4))
# Prints (0, 1, 2, 3)

You can even convert any collection (such as a dictionary, set or frozen set) into a tuple.

# dictionary keys into tuple
T = tuple({'name': 'Bob', 'age': 25})
# Prints ('age', 'name')

# set into tuple
L = tuple({1, 2, 3})
# Prints (1, 2, 3)

Two Machine Learning Fields

There are two sides to machine learning:

  • Practical Machine Learning:This is about querying databases, cleaning data, writing scripts to transform data and gluing algorithm and libraries together and writing custom code to squeeze reliable answers from data to satisfy difficult and ill defined questions. It’s the mess of reality.
  • Theoretical Machine Learning: This is about math and abstraction and idealized scenarios and limits and beauty and informing what is possible. It is a whole lot neater and cleaner and removed from the mess of reality.
